Start by setting your Instant Pot to the sauté function. Add 1 teaspoon of extra virgin olive oil and let it heat up. Once hot, add 1 pound of lean ground beef, turkey, or chicken. Cook until browned, breaking it apart with your spatula. This should take about 5-7 minutes.
Once the meat is fully cooked, sprinkle in 1 teaspoon of cumin and stir well to combine. Next, pour in 1 cup of salsa for the meat mixture, and mix everything until the meat is well coated. Allow the mixture to simmer for a couple of minutes.
Now it’s time to layer your lasagna! Start by spreading 16 ounces of refried beans evenly across the bottom of the pot. Then add half of the meat mixture, followed by 1 cup of salsa for layering. Next, place two tortillas on top, followed by half of the 8 ounces of shredded cheddar cheese. Repeat these layers with the remaining ingredients, finishing with a layer of cheese on top.
Seal the Instant Pot lid and ensure the valve is set to sealing. Set the pressure cook function to high for 10 minutes. Once the cooking time is complete, allow for a natural pressure release for 5 minutes before manually releasing any remaining pressure.
Carefully remove the lid and let the lasagna sit for a few minutes. This will help it set slightly, making it easier to serve. Use a spatula to cut into squares and serve with your favorite toppings such as sour cream, diced tomatoes, avocado, or fresh cilantro.
