On a good sized piece of Alum. Foil.
Cut in slices 1/4 or so Yellow Squash, zucchini, Bannana pepper, Onion and green pepper.
Salt and pepper, a little cajun seasoning and a little olive oil over the top.
Fold the foil and bring up the ends so the liquid does not escape.
Place on grill at med heat for 15-18 Min.
Good.
Joe
PS Heavy foil works best.
