Corn and Black Bean Salad with Zucchini

1 Preheat a grill pan to high and heat for 5 minutes. (Alternatively, preheat grill to high.) Carefully brush corn, zucchini halves and onion slices all over with olive oil. Using tongs, place corn and zucchini halves, cover and grill until the corn is charred all over and zucchini is tender, about 8-10 minutes, turning the corn often and flipping zucchini halves once after 4 minutes. Add onion slices after 4 minutes and flip them after 2 minutes.
2 Let cool and use a large knife to cut corn kernels off the cob into a large bowl. Chop zucchini halves.
3 Mix corn, zucchini, red onion, black beans and feta cheese in a large bowl (Alternatively, divide among 4 serving bowls or plates).
4 Add avocado dressing and season with salt and freshly ground black pepper to taste. Enjoy!
