Obviously. But you also need the time to cook and not to have the appetite of a 10 year old. The latter, from what I've observed, is quite common in grown adults.
Why "cook”? In a hurry I grab a can of bean, a carrot, a branch of celery, some rye bred and a square of tofu. No prep or tooling except a spoon for the beans.
Something hot at the snack? Grab a veggie pad thaï, veggie pizza, veggie burger (with actual veggies), daal with veggies…
