Unique Perogies Style Shepard Pie

1 lb extra lean ground beef
1 onion, diced
1 clove garlic, crushed
1 can condensed mushroom soup
1/2 tsp thyme
1/2 tsp basil
1/2 tsp oregano
1/4 tsp ground pepper
2 cups frozen mixed vegetables
1/2 package of perogies
1 cup shredded mozzarella cheese

Cook ground beef, onions and garlic on medium heat in a large non-stick skillet until meat has browned. Add soup, spices and vegetables. Heat for another 5 minutes until vegetables have thawed. Pour into a 3-quart casserole dish and arrange frozen perogies on top. Sprinkle with cheese. Bake at 350F for 35-40 minutes until perogies have cooked and cheese has browned. Faster version: microwave covered on high for 10 minutes, then place under a broiler for 3-5 minutes to brown the cheese.
