Tip

Although fresh oysters will always taste best, canned oysters work just as well. This option is ideal if you can't find fresh oysters. In the grocery store, canned oysters are usually sold next to canned tuna and sardines.

Step 1

Preheat broiler on high. Grease a casserole or baking dish.

In a large skillet over medium heat, melt 2 tablespoons of butter. Add the onion, bell pepper and garlic. Cook until the vegetables are tender, about 5 to 7 minutes.
