I definitely will stop here again! Good veggies in the culinary no man's land of the C terminal at McCarran. The only other food I could find which was vegan in this terminal was the veggie burger at Burger King and a veggie burrito (hold the cheese) at some Mexican chain.
If you are looking for truly healthy food, get the vegetable "side" topped with marinara. Not overcooked, but lightly steamed pieces of broccoli, winter squash, zucchini, and carrots. Very high nutrient to calorie ratio, healthy eating in the midst of slot machines and fast food junk. Plus, right across from the counter is a bunch of tables right along the wall which are relatively private.
