Some things taste much better than they photograph and this is definitely one of them.

For starters, just look how bland everything looks.  The purple peppers turn this translucent looking gray.  Yet they taste great.

This used:

Purple Peppers
Red Onion
Zucchini
Yellow Squash
Cherry Tomatoes
Canned Artichokes
Olive Oil
and Lemon Juice
salt & pepper too.
Maybe a few hot pepper flakes
