Greek Sausage Pita Pizza

2 garlic cloves, minced
4 whole pita breads
2 plum tomatoes, seeded and chopped
1 medium ripe avocado, peeled and cubed
½ cup crumbled feta cheese
1 small cucumber, sliced
½ cup refrigerated tzatziki sauce

Preheat oven to 350°. In a large skillet, cook sausage and garlic over medium heat 6-8 minutes or until no longer pink, breaking up sausage into large crumbles; drain.

Meanwhile, place pita breads on ungreased baking sheets. Bake 3-4 minutes on each side or until browned and almost crisp. Top pita breads with sausage mixture, tomatoes, avocado and cheese. Bake 3-4 minutes longer or until heated through. Top with cucumbers; drizzle with tzatziki sauce.
