Too hard to just pick one but I'm going to mention the moringa tree.
The leaves are edible and has protein. The seeds and roots are also edible. Fast-growing. Tropical or subtropical tree but can be grown as an annual in colder regions. The seeds have been used to purify water. Nitrogen fixer. Seed pods also edible. Easy to cut a limb and make a new tree. In the USA it can grow in places like Arizona and Florida.
