Bread of choice
You can use any vegetable that you want as long as you can grill them. I didn't have zucchini this time so I just left it out - but I have used squash instead of zucchini also and that was really good, too.
Peel and slice the eggplant and zucchini or squash. Slice the tomato and onion.
Preheat your grill while slicing veggies. Place veggies on grill and heat thoroughly. I like to brown them slightly so that they get soft.
While veggies are grilling, slice choice of bread in half lengthwise and brush olive oil on the insides. Place finished veggies on top shelf of grill to keep warm while you grill the bread. The bread will only take a few minutes.
Spread pesto sauce on bread and then put veggies of choice to make a sandwich. Add a side of pasta or cottage cheese or fruit to keep it healthy. Here's a picture of the finished product ~
