In a food processor, add onion and garlic and process until minced, about 1 minute. Add beef, lamb, oregano, cumin, and salt and pulse until well mixed, about 1 minute.

Transfer meat to the prepared pan and press down evenly. Cover and let meat marinate in the fridge for at least 30 minutes or for up to 12 hours.

Bake for 30 minutes, until meat reaches an internal temperature of 145 degrees F. Remove from the oven and let cool. Transfer meat to a cutting board and cut into thin slices.

To assemble gyros, divide meat, red onion, cherry tomatoes, and feta cheese, if using, among 6 pita breads.

Place mushrooms in the bowl of a food processor and pulse until finely chopped. Transfer to a large mixing bowl.

Add ground beef and Worcestershire sauce to the mushrooms and mix until well incorporated. Form into 10 equal patties.

Place a large nonstick pan over medium-high heat. Spray pan with cooking spray and gently place patties on the hot skillet. Cook until browned, about 5 minutes per side.

Serve hot on buns with mixed greens, tomatoes, and pickles, if using.

Place a large skillet over medium-high heat. Add olive oil and onions and cook until onions become translucent, about 5 minutes. Add garlic and cook until fragrant, about 1 minute more.

Bake until zucchini is tender, about 15 to 25 minutes.
