Last night, I copied a GREAT sandwhich that I had at a restaurant a month ago. I didn't have all the veggies on hand that they served in their sandwich, but it still turned out great.
Bread (The restaurant served it on ciabatta, but I made herb bread in the breadmaker)
Sweet potato, cut into long 1/4 inch thick slices
Zucchini, cut into long 1/4 inch thick slices
Tomato, sliced into 1/2 inch thick rounds
We were out of propane, so I couldn't grill the veggies over the flame. Instead, I put them on a tin foil lined baking sheet, drizzled them with olive oil, salt and pepper, and baked them at 350' for 10 minutes. I toasted the bread, and made a spread of equal parts prepared pesto and mayonnaise. Layer all the veggies, and ta-dah! A delicious sandwich! We had it with a Dill Pasta Salad.
For the record, the restuarant also had summer squash, red pepper, and gouda cheese on their sandwich and it was delish. Mine could have used a little cheese, but was good nonetheless.
