An "average meal" in a hospital can refer to a healthy meal intended for an omnivore person with no special dietary needs. Vegan meals in hospitals, which do not contain meat, fish, eggs and milk, should contain enough iron and protein from plant sources.
Foods high in protein but also in fat include most nuts and seeds.
Maybe the most appropriate beverages are those that are low in sugar: plain or mineral water, vegetable juices, tea.
Vegan patients who stay in a hospital for several months may also benefit from vitamin D and B12 supplements.
