Preheat oven to 350º F. In a cast iron skillet or other pan, heat oil, add onions, peppers and garlic. Saute until onion is translucent.

Add broccoli, potatoes and ham. If using cast iron skillet, pop into oven, or transfer from frying pan into casserole dish. Bake for 20 min. Check and submerge any potatoes that are sticking out. Bake for an additional 15 minutes. Let stand a few minutes before serving.
