OK, tried everthing else. Either you lose vegetables through the grate or they get stuck to whatever you put on the grill to prevent this, or you just end up frying or steaming them on the grill. Enter these screens from Walmart, which you can reuse if your vegetables are covered in olive oil, and therefore don't stick, as in the picture of tonight's dinner above. (Click on image to purchase screens--only a buck apiece!) P.S. Covered these with tzatziki!
