I usually make this one on the grill, but since it's a bit wet out, I'm broiling in the oven instead. It's simple, healthy and delish! Just slice vegetables of your choice (I used eggplant, zucchini, yellow squash and red peppers) thinly in a single layer on a baking sheet. Drizzle with olive oil, salt, and pepper. Then pop in the oven for 10 mins on 500ish degrees.
Then layer bread (I used large sourdough english muffins) with pesto and mozzarella.
Finally, layer with the roasted vegetables.
...and voila! Simple and yummy lunch or dinner!
