Prep all ingredients per instructions above.

Preheat the oven to 375°F (190°C).

Greek Meatballs: In a bowl, combine ground beef, ground lamb, breadcrumbs, red onion, minced garlic, beaten egg, oregano, cumin, salt, and black pepper.

Shape the mixture into meatballs, about 1 inch in diameter.

Heat olive oil in a skillet over medium heat. Brown the meatballs on all sides.

Transfer the meatballs to a baking sheet and finish cooking in the preheated oven for about 10-12 minutes or until cooked through.

Tzatziki Sauce: Grate the cucumber and drain excess liquid.

In a bowl, combine Greek yogurt, grated and drained cucumber, minced garlic, chopped fresh dill, olive oil, salt, and black pepper.

Refrigerate the tzatziki sauce until ready to serve.

Arrange tomato slices on a serving plate. Drizzle with olive oil, sprinkle with dried oregano, and add a pinch of salt.

Prepare Pita Bread: Warm the pita bread in the oven or on a skillet.

Place meatballs on plates. Spoon tzatziki sauce over the meatballs. Serve with tomato slices, chunks of feta cheese, Greek olives, and pita bread on the side. Enjoy with a soda, over ice if desired.
