Add the rolled oats to a blender and blend them to make oat flour.
Dice the white onion. After that, lightly spray a pan with olive oil over medium heat and sauté the onions. When the onions are almost done cooking, crush the cloves of garlic and add them to the pan. The onions are done cooking when they are translucent.
Add the ground turkey breast, cooked onions and garlic, corn, black or pinto beans, oat flour, taco seasoning, eggs, and 1/4 cup of the red salsa to a large bowl. The rest of the salsa will go on top of the meatloaf. Thoroughly combine these ingredients in the bowl.
Form a 2-3 inch high meatloaf on a sheet pan with parchment paper. Add the remaining 1/2 cup of red salsa on top of the meatloaf.
Cook the meatloaf at 350℉ for 40-50 minutes, or until cooked through.
Once cooked, sprinkle the light Mexican cheese blend on top. Bake the meatloaf for up to five more minutes or until the cheese is melted.
When the Mexican meatloaf is done, sprinkle the green onions and cilantro on top and enjoy! Serve with extra salsa on the side if desired. We were able to get 8 slices that were about 1.5 - 2 inches each from this meatloaf.
