Deep Dish Cowboy Pie

4 cups all-purpose flour
1 3/4 tablespoons baking powder
3/4 teaspoon salt
3/4 cup vegetable shortening
1 1/4 cups milk
1/2 cup Cheddar cheese
1/4 cup diced green chives or green onions
1 1/2 pounds lean hamburger
1/2 cup chopped onion
Salt and pepper to taste
1/4 teaspoon garlic powder
1 (8 ounce) can tomato sauce
1 ripe tomato, peeled and sliced
1 cup sliced fresh mushrooms
1 1/2 cups shredded mozzarella cheese

Heat oven to 375 degrees F.

In a large bowl combine the flour, baking powder, salt and vegetable shortening. Cut shortening into dry ingredients with a fork or pastry blender. Add cheese, chives, then milk. Mix with a fork to form dough. Pat dough on bottom and up sides of a greased 10-inch plate. Roll out remaining dough and make biscuits. (Will make 10 to 12 biscuits.) Set aside.

In large skillet, brown meat and onion. Drain grease. Add seasonings and tomato sauce. Put meat mixture in uncooked pie shell. Top with sliced tomatoes, mushrooms and cheese. Bake for 45 to 60 minutes.
