Southerners are in love with sweet onions, and the sweetest variety is grown near us - in Vidalia, Georgia. Since Vidalias have become so popular, everyone - including me! - seems to be developing new onion recipes.

Ingredients

  • 3 large sweet white onions, sliced
  • 2 tablespoons butter
  • 2 cups shredded Swiss cheese, divided
  • Pepper to taste

  • 2/3 cup whole milk
  • 1 teaspoon soy sauce
  • 8 slices French bread, buttered on both sides
