Dietitian Rachel Paul, PhD, RD (@collegenutritionist on Instagram), wrote in a post, "LUNCH should be FILLING! It's no good to eat an unsatisfying lunch... only to get hungry soon after & not be able to concentrate on work or school! Fill your salad with good protein and fats - and use those non-starchy veggies to add a lot of VOLUME."
Nonstarchy veggies include greens like kale, spinach, and arugula and veggies such as cucumbers, courgette, asparagus, broccoli, and cauliflower.
