Coat an 11-inch by 7-inch casserole dish with cooking spray.
Heat oil in a frying pan and add onion & bell pepper. Saute till tender.
Mix the onion/pepper mixture with corn, beans, tomato sauce, tomatoes & Worcestershire sauce. Taste and add salt & pepper if needed.
Pour it all in the casserole dish and cover the top with a layer of bacon.
Cover and bake for 50 minutes, remove cover and bake 10 minutes more or until bacon crisps up.
*** To make using fresh vegetables:
Cover the BOTTOM of the dish with the bacon then layer with fresh lima beans, fresh sliced tomatoes, chopped onion and green pepper, fresh white corn (cut off cob, of course), another layer of sliced tomatoes and another layer of bacon on top. Bake as above.
