heaven between two slices of bread

sorry, no photo this time. i didn't think to take a photo of "just a sandwich." oh but this is such a yummy sandwich...

Caprese Panini
makes 2 sandwiches

1 tablespoon olive oil
3/4 cup diced tomatoes
pinch of red pepper flakes
1/2 teaspoon balsamic vinegar
4 slices of sourdough or whole wheat bread (note: i was skeptical but tried the whole wheat because that was what i had on hand -- and so very good!)
1/2 cup pesto, purchased or homemade
6 ounces fresh mozzarella, thinly sliced
salt and pepper

Heat oil in a nonstick skillet over medium-high heat. Add tomatoes and red pepper flakes; saute until just starting to break down, about 3 minutes.

Off heat, add vinegar. Brush oil on one side of each slice of bread; spread the other sides with pesto. Arrange mozzarella and tomato mixture on two slices of bread, then sprinkle with salt & pepper. Top with another slice of bread, oil side up.

Toast sandwiches in a panini press. Or you can toast them in a skillet, a heavy skillet on top of the sandwich as a weight, or by pressing down continually on the sandwich with a spatula (this is the method i used). Cook over medium heat. When first side is finished, flip and reweight to finish.
