A fresh-forward feast on its own, but feel free to work in marinated mushrooms, mixed greens, or the cheese of your choice.
Slice focaccia or panini buns open. In a bowl, toss peppers, eggplant, and artichoke with pesto to coat. Arrange veggies on bread and crumble goat cheese over. Sprinkle with pine nuts and sandwich together. Press on a heated grill press or wrap in foil and heat in a 350 F (180 C) oven until warm through, about 12 to 15 minutes. Slice and serve.
