Caramelized Onion, Lettuce and Tomato Sandwich
- 1 large onion, sliced
- 3 tablespoons olive oil
- 1-2 large tomatoes, sliced into thick slabs
- 8 leaves of butterhead lettuce
- 4 tablespoons mayonnaise
- 8 slices sourdough bread
Heat a skillet over medium-low heat, and add olive oil and onions. Let them caramelize for about 15 minutes, and then turn the heat up a bit for the last few minutes to get them a bit crispy.
Spread mayonnaise on the slices of bread. Add a slice (or slices) of tomato to cover one half.
Sprinkle the tomato with salt and pepper.
Stack a few crunchy pieces of lettuce atop the tomato, then add onion, and put the lid bread on.
