Brown the beef: In a large skillet over medium-high heat, brown the ground beef. Break it up with a spoon as it cooks.

Add vegetables: Add the chopped onion and green bell pepper to the skillet. Cook until softened, about 5 minutes.

Season: Stir in the chili powder, cumin, garlic powder, salt, and pepper.

Simmer: Pour in the tomato sauce and water. Bring to a simmer and cook for 10-15 minutes, or until the sauce thickens.

Serve: Warm the corn tortillas according to package instructions. Fill the tortillas with the beef mixture and your desired toppings.

Enjoy your delicious beef tacos!

Tip: For a spicier taco, add a pinch of cayenne pepper to the seasoning mix.
