I would like to offer up what I do for side dishes.
The first is to grill corn on the cob in the husks. We soak the corn in water and then place it directly on the grill. I like my corn crunchy, so it only takes... 20 - 30 minutes. Mmmm. I also top it with the Becel toping spray. 5 squirts for 0 calories and it gives that buttery feeling.
The second is a family favourite. Grilled asparagus. We very lightly brush it with EVOO and then sprinkle lemon pepper on it. OMG. SO good. We have to cook two bunches just for the three of us!!
Anyhow - these are two staples in our house in the summer. The best part is, with these two side dishes I don't need to make potatoes or rice!
