- 4 portabella caps - (3" to 4" dia)
- Salt to taste
- 1 tablespoon corn or peanut oil
- 4 slices American or Jack cheese
- 4 toasted hamburger buns
Cut off any residual stems from the caps so that the caps will lie flat. Lightly salt the grill side of the caps.
Place a 10- to 12-inch non-stick pan over high heat and add the oil. Before the oil starts smoking, add the caps, gill-side down. Reduce the heat to medium and let the caps cook for 2 minutes.
Turn the caps and cook for another minute. Carefully place the cheese inside the caps and cover the pan with a lid (it does not have to be tight fitting) and cook for another minute, until the cheese is melted.
Transfer the caps to the buns and add any of your favorite toppings: lettuce, slices of tomato and onion, and, of course, relish. Cover with the other half of the bun and serve.
This recipe yields 4 servings.
Variation: Chop the portabella stems you sliced from the caps and saute them in a little oil with some sliced onions and minced garlic. When the onion mixture is well wilted and golden brown, remove from the pan and place on top half of the bun. Then cook the caps and place them on top of the onion mixture. For a Pizzaburger, add a little warmed tomato sauce, flavored with oregano or basil.
You can also prepare regular hamburgers and simply place these portabella burgers on top.
