I think it's the colors. Peppers are like looking at a living, breathing color wheel. Deep and bright reds, purple, spring greens to light yellow-greens, bright oranges and yellows. Peppers are just a feast for the eyes! And for the mouth - from super mild to Call-911-I'm-Melting-From-The-Inside-Out! Crisp, crunchy peppers are delicious!

Cut peppers into 1” chunks and onion and cucumber into 1/4” slices. Pinch off small 1” chunks of the mozzarella and add to peppers. Then put in olives and tomatoes. Stir in vinegar, oil, salt and pepper. Let sit in the friger-frater (that's what my kids used to call it) for at least 30 min before serving. Stir well again before serving.
