1/2 cup chili sauce
1/4 cup lightly packed brown sugar
3 tablespoons Worcestershire sauce
1 teaspoon Accent
1 tablespoon grated Parmesan cheese
Dash of Tabasco sauce

Slice onions into thin rings and place in a casserole dish. Make a sauce by combining remaining ingredients. Simmer the sauce very slowly for 5 minutes. Pour sauce over onion rings and bake at 350 degrees F until onion is tender, or about 30 minutes. Stir occasionally while baking.
