Hot Dog Pitas

This recipe is from an old Better Homes & Gardens magazine. I haven't seen a similar pita filling before.

Hot Dog Pitas

1 (8 oz.) can tomato sauce
1 green pepper, cut into 1/2-inch pieces
1/2 cup shredded carrot
1 (4 oz.) can sliced mushrooms, drained
1 tablespoon Dijon-style mustard
1/2 teaspoon onion salt
6 frankfurters, chopped
3 large pita bread rounds, halved
1/2 cup shredded cheddar cheese ( 2 ounces)

In a 10-inch skillet combine first 6 ingredients and 1/3 cup water. Bring to boiling; reduce heat. Simmer, uncovered, 10 minutes. Stir in frankfurters; return to boiling. Simmer, uncovered, about 5 minutes or till pepper is crisp-tender. Spoon mixture into pita halves. Sprinkle shredded cheese atop each. Makes 6 servings.
