Preheat oven to 425 degrees. Spray a 13" x 9" baking dish with cooking spray and set aside.
Place asparagus, tomatoes and garlic into a large mixing bowl. Drizzle with olive oil and vinegar then toss to coat. Sprinkle with sugar, salt and pepper then transfer to the prepared baking dish.
Roast 16–22 minutes, depending upon thickness of asparagus and desired tenderness—toss veggies once or twice while roasting for even cooking. Check doneness. Remove from oven, transfer to serving dish and enjoy!
One Last Thing
Watch your cook time! Thinner asparagus take less time whereas thick ones like ours take a bit longer.
