Preparation: Prepare barbecue (medium high heat). Grill bread until slightly charred, 1 to 2 minutes per side. Remove to bowl.
Preheat oven to 425°F. Add squash, zucchini and asparagus to a sheet tray. Drizzle with olive oil, salt & pepper and roast for about 10 minutes until vegetables are cooked through but not mushy.
