Ground Beef Gyros

I totally forgot about this recipe until last week. I love these and lest I forget to post this later, I'm posting it now. Enjoy!

Ground Beef Gyros
Serves 6

3/4 pound extra lean ground beef -- cooked and drained
3/4 cup plain low-fat yogurt
1/4 cup cucumber -- finely chopped
1/2 teaspoon dill weed (I add more b/c I'm crazy like that)
1 tablespoon vegetable oil
3 medium onions -- sliced into rings
1 1/2 teaspoons garlic powder
1/4 teaspoon dried oregano
6 whole wheat pita breads -- warmed
1 small tomato -- chopped

Combine yogurt, cucumber and dill weed. Cover and refrigerate. Heat
oil in large nonstick skillet over medium-high heat 2 minutes. Add
onions; cook 2 minutes, stirring occasionally. Add beef, garlic
powder and oregano; cook 4 minutes or until heated through, stirring
occasionally.

Stuff beef mixture in warmed pita breads and serve with yogurt sauce.
