1 Green or Red bell pepper sliced into circles
1 tomatoes sliced into rounds
1/2 sweet yellow onion sliced into circles
1 Tbsp Yellow mustard
1-2 Tbsp horseradish depending on your taste
1/2 cup Butter
Salt and pepper
In a casserole dish layer the green beans first. Layer the onion then the peppers followed by the tomato's. Salt and pepper everything.
In a microwave safe bowl melt the butter and then stir the horseradish and the yellow mustard. Stir it well and then drizzle the butter mixture over the contents of the casserole dish. Bake covered with tinfoil at 375 degrees until the peppers are done (about 20 mins.) Uncover and bake an additional 7-10 minutes to let the tomatoes get some color.
