I love me a packet of asparagus on the grill but I take it up and away from the flame for more of an indirect cook, and load the butter on it. just don't cook to long or you will be eating rubber. lol.
scallops sounds good, never tried them on the grill.
This is what I cooked the wife tonight. Ribeye on the grill topped with smoked mozzarella cheese and mushrooms. mushrooms were cooked first in a packet on the grill. The corn was also cooked on the grill with the husk on until it was nice and black and burnt.
