Mushroom Veggie Burgers - cooking recipe

Ingredients

1 tablespoon olive oil
1 1/2 cups moderately finely chopped onions (about 1 large onion)
3 small garlic cloves, finely minced
4 cups coarsely chopped portabella mushrooms (about 2 large mushrooms)
1/4 teaspoon salt
1/8 teaspoon fresh ground black pepper
1 cup Italian seasoned breadcrumbs
2 large egg whites
bun, and condiments of your choice

Preparation

Heat olive oil in 12\" skillet over moderately high heat for 1 minute. Add chopped onion and garlic and saute, stirring occasionally, until limp and golden- about 3 minutes.
Add mushrooms and saute, stirring now and then, until mushrooms soften and brown- about 4 minutes. Transfer mushroom mixture to a large bowl and cool 10 minutes.
Using wooden spoon, mix salt, pepper and bread crumbs into mushroom mixture. Add egg whites and mix thoroughly.
Scoop up mixture by 1/2-cup measure, then using hands, shape into 4 patties about 3/4\" thick.
Wipe out skillet, spray with nonstick spray, and set over moderate heat. Add patties and brown about 3 minutes on each side.
Serve on buns and add desired condiments.
