These are so easy to make and an excellent side for a grilled steak.
I soften the zucchini in the microwave for a few minutes. Scoop the flesh out of the shell and chop it with a small tomato and some onion.
Place the filling back in the shell and top with shredded parmesan.
Wrap in foil and place on the grill for about 20 minutes.
Bon Appetit!
