Spinach and Ground Beef Burgers with Avocado

In a large bowl, combine ground beef, finely chopped spinach, minced garlic, chili powder, salt, and black pepper.

Mix the ingredients thoroughly until well combined.

Divide the mixture into equal portions and shape each portion into a patty.

Heat olive oil in a skillet over medium heat.

Place the patties in the skillet and cook for about 5-6 minutes on each side, or until desired doneness is reached.

While the patties are cooking, slice the tomatoes and avocado, and prepare the lettuce leaves.

Once the patties are ready, assemble the burgers by placing each patty on a lettuce leaf.

Top the patties with a slice of tomato and avocado.

Serve immediately with your choice of sides.
