Readers know that my favorite grilled veggies are eggplant and corn (maize to our readers overseas).
Drizzled with a little olive oil and salted, all of these are tasty: red onion, peppers, asparagus, tomato, summer squash slices, potato slices, pineapple, apple, etc. Anything can be grilled, and it keeps you outdoors.
Best way to grill corn on the cob? Soak them in the husks in a bucket of water for an hour or two, then strip off the roughest outer husks, then toss on grill. When the husks brown a little and the flossy stuff burns, they are done. A little salt to serve - no butter.
