In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced sweet onion and bell pepper. Sauté for about 5 minutes, or until the onion is translucent and the bell pepper is tender. Add the minced garlic and cook for an additional minute until fragrant.
Add the ground turkey to the skillet. Use a spatula to break it apart as it cooks. Continue cooking for about 6-8 minutes, or until it’s no longer pink.
Stir in the ground cumin, smoked paprika, chili powder, garlic powder, salt, and pepper. Mix well to ensure the turkey and veggies are evenly coated in the spices.
Sprinkle the tablespoon of flour over the turkey mixture and stir to combine. Gradually pour in the chicken stock, stirring constantly to avoid lumps. Allow the mixture to simmer for about 3-5 minutes until it thickens slightly.
Sprinkle the shredded cheddar cheese evenly over the turkey mixture. Cover the skillet and let it cook for another 2-3 minutes until the cheese is melted and bubbly.
While the cheese is melting, prepare your toppings. In a bowl, combine quartered cherry tomatoes, diced sweet onion, chopped cilantro, lime juice, and a pinch of salt and pepper. Set aside.
Once the cheese is melted, remove the skillet from heat. Serve the turkey mixture with tortilla chips, shredded lettuce, pickled onions, cotija cheese, avocado slices, and lime wedges on the side. Let everyone build their own nacho creations and enjoy!
