In a large skillet, heat the olive oil over medium heat. Add the chopped sweet onions and sauté until translucent, about 3-4 minutes.
Add the ground turkey and ground beef to the skillet. Use a wooden spoon to break up the meat while cooking until browned, about 7-10 minutes.
Sprinkle in the chili powder, cumin, garlic powder, oregano, salt, and pepper. Stir well and cook for an additional 2-3 minutes.
Add the drained chili beans and the can of Ro-Tel. Stir and let it simmer for 5 minutes.
Warm the corn tortillas either by frying them in a skillet or warming them over a low flame until pliable.
Spoon the meat mixture into the warmed tortillas and top with desired fixings like lettuce, tomatoes, sour cream, avocado, and cheese.
