2 Tablespoons olive oil 1 pound hamburger 1 cup chopped onion 1 clove garlic, mashed 2 (8-ounce) cans tomato sauce 2 cups dry red wine (*see note below) 1 cup water 1 pound spaghetti, uncooked 1 1/2 teaspoons chili powder 1 1/2 teaspoons salt (*see note below) 1/4 cup grated Parmesan cheese
Heat pressure cooker and add oil.
Lightly brown hamburger, onion and garlic, stirring occasionally to separate meat. Add all remaining ingredients except cheese. Toss uncooked pasta in liquid so it separates (if spaghetti is to long break strands in half before adding). Close cover securely. Place pressure regulator on vent pipe and cook 7 minutes for well-done spaghetti, 6 minutes for al dente.
Cool cooker immediately. Stir cheese into mixture before serving. Makes 4 to 6 servings.
