Ingredients:

• 1 lb white fish fillets (such as tilapia, cod, or mahi-mahi) 
• 1 tablespoon olive oil 
• 1 teaspoon chili powder 
• 1/2 teaspoon cumin

Instructions:

1. Prepare the Fish: Pat the fish fillets dry with paper towels. In a small bowl, mix together olive oil, chili powder, cumin, garlic powder, salt, pepper, and lime juice. Rub the spice mixture over the fish fillets. 
2. Cook the Fish: Heat a skillet over medium-high heat. Add the fish fillets and cook for 3-4 minutes per side, or until the fish is cooked through and flakes easily with a fork. Remove from heat and flake the fish into bite-sized pieces.
