Sure you could make a grilled pasta salad with the usual suspects: zucchini, yellow squash, bell peppers. But why not change it up with crunchy bitter broccoli rabe and a bright and sweet tomato vinaigrette? Fresh mozzarella and the sweetness of grilled red onions helps to balance the tangy dressing. Pasta salads can often be overdressed, so we recommend tossing half the vinaigrette with the pasta mixture and adding a little bit more at a time, tasting as you go, until its dressed just to your liking. Wagon wheels are fun but you can use any short pasta shape you like.
