Thinking of going Italian. Well, here is one for the squash, zucchini, or eggplant. It is simple and easy. Remember though to cut your squash length wise instead of little round cuts. The Eggplant is ok to slice because of its size. It is the smaller squash than tender and less seedy, so thus most chefs prefer that to the larger ones.
3 Tablespoons of Olive Oil
healthy tablespoons of each of the following
Garlic (Fresh and use a press)
Salt and pepper to taste
Use this on the above about 1 and one half hours before you grill it. Hopefully the charcoal or wood is your choice but it is also good on propane and gas grills.
