Artichoke-Spinach Burgers

The topping of roasted tomatoes and feta adds both sweetness and depth of flavor to these vegetarian burgers. They’re ready in almost no time, but in a pinch, you can just top the burgers with raw tomatoes, or use a few sun-dried tomatoes if fresh tomatoes aren’t in season. For the best results, use artichoke bottoms instead of hearts, as they do a better job of binding the burgers together.
