I've worked at Costco for 18 years. Here are 8 of my favorite prepared meals to get there for my family.

The Kirkland Signature meatloaf is by far my favorite version of the dish I've come across. The meatloaf is made from scratch in Costco's deli using the Kirkland Signature ground beef, eggs, onions, seasoning, and glaze. The meatloaf comes with buttery mashed Yukon potatoes.

The best part about preparing this dinner is that you only need a sheet tray and foil. I simply place the meatloaf on a tray, cover it with foil, and heat it in the oven at 375 degrees Fahrenheit for about an hour. I like to think of this as a set-and-forget-it meal that can feed about three to four people in my family. 

You can buy the Kirkland Signature meatloaf with mashed Yukon potatoes for $4 per pound.

The Kirkland Signature chicken street tacos are a convenient, easy dinner option. The kit comes with chicken, cheese, tortillas, salsa, cilantro-lime crema, lime wedges, and shredded cabbage.

All you have to do is heat up the tortillas and precooked chicken. I place my chicken in the air fryer for about five minutes at 350 degrees F, though you can heat it in a microwave, pan, or skillet on medium heat. I also like to warm my tortillas on a frying pan, flipping until warm.

You can find the Kirkland Signature chicken taco kit in the deli section for $5.50 per pound.

Chicken Alfredo is a family favorite because it's fast, convenient, and tasty. The Kirkland Signature chicken Alfredo is made with penne pasta, chicken-breast strips, Alfredo sauce, mozzarella, and Parmesan.

I like this dish because it's very filling, is smothered in a creamy, thick sauce, and I can taste the cheese in every bite.

All I have to do is remove the lid, add foil, place the tray onto a cookie sheet in the center of the oven at 400 degrees F, and dinner is ready in one hour. You can find the chicken Alfredo for $5.50 per pound, which is usually between $17 and $20 total.

My family likes to eat the Kirkland Signature stuffed bell peppers at least three times a month, as they're a convenient, filling meal. The peppers are stuffed with seasoned ground beef, tomato sauce, shredded cheese, and rice, and topped with parsley.

I also love that they're so easy to bake in the oven. I remove the plastic lid from the tray, cover it with aluminum foil, and place the whole thing in the oven at 400 degrees F for about an hour, or until the internal temperature reaches 165.

I've made my own stuffed bell peppers before but I find that this option is easier and costs less. You can find the stuffed bell peppers for $5 per pound.

I'm a big fan of the Kirkland Signature beef bulgogi Korean BBQ. I think it's a little on the sweet side but if you don't mind it, then this is a must-try.

The container comes with enough marinated beef and sliced onions to feed about five people in my family. I like to serve the beef with some white rice.

I usually add the beef bulgogi to a skillet over medium heat and stir it until it's fully heated through, which takes about 10 to 15 minutes.

You can find the beef bulgogi Korean BBQ in the deli section for $8 per pound.

The chicken-quesadillas container comes with everything you need: Large flour tortillas stuffed with chicken and cheese, red salsa, two small packs of Kirkland Signature guacamole, and a container of sour cream.

The directions on the package say to heat 1 ounce of oil and cook the quesadillas for 2-1/2 minutes on each side, or until the internal temperature reaches 165 degrees F. I tried mine a different way and placed the quesadillas in the microwave for 45 seconds and then popped them in the air fryer at 350 degrees F for five minutes. The tortillas came out crispy but not overly done.

I really like how stuffed the quesadillas are with chicken and cheese. You can find these filling Kirkland Signature quesadillas for $6 per pound, or about $16 per container.

The Kirkland Signature macaroni and cheese is one of the cheesiest versions of the dish I've tried.

The flavors of the Romano and Parmesan are great but I incorporate some corn and diced jalapeños to elevate the dish even more. It's a great comfort food that can easily feed eight or more people.

To make it, I cover the tray with foil, place it onto a baking sheet, and pop it in the oven at 400 degrees F for about 40 to 60 minutes.

You can find the Kirkland Signature mac and cheese for $3.50 per pound, which is about $13 to $15 per tray.

The Kirkland Signature rotisserie chicken seems to be a go-to dinner for customers, and I enjoy it too.

Just one bird can serve as a starting point for so many different dinners, such as chicken salad, enchiladas, or even sandwiches. I think it's one of the most convenient meals at the best deal.

You can grab a 3-pound rotisserie chicken for just $5.
