In a skillet over medium heat, add the ground beef and cook until browned, about 5-7 minutes.

Drain excess fat and add chili powder, cumin, garlic powder, onion powder, salt, and pepper. Stir to combine and cook for another 5 minutes.

Warm the corn tortillas in a separate skillet or microwave until pliable.

Assemble the tacos by adding the cooked meat to each tortilla and topping with onion, cilantro, and diced tomatoes.

Serve with lime wedges on the side.
