Start by placing your dressing in the bottom of the mason jar. Pictured is my homemade ranch, but a vinaigrette will spread easier when you go to eat. My favorite to use generally is my homemade honey mustard vinaigrette. Next come the veggies that can hold up to soaking in the dressing. Place in the tomatoes, carrots, onions, radishes and broccoli florets, in that order.
