Let rolls rise until doubled, following package directions. Meanwhile, in a small skillet, saute the red pepper, mushrooms, broccoli, onion and garlic in 2 teaspoons oil for 2-3 minutes or until crisp-tender. Combine the cheeses and parsley; stir into vegetables.
On a lightly floured surface, roll each dinner roll into a 7-in. circle; brush with salad dressing. Spoon vegetable mixture onto half of each circle; spread to within 1 in. of edges. Fold dough over filling; pinch edges to seal.
Place on an ungreased baking sheet. Brush with remaining oil. Bake at 350° for 15-20 minutes or until golden brown.
