Brown hamburger meat (with chopped onion if you like it.) Drain meat. Put browned meat into a 13x9x2 pan, spread evenly. Spread 2 cans of green beans evenly as possible over the hamburger meat. Then spread the 2 cans of cheese soup over it all. There will be a layer a meat, then a layer of green beans, then a layer of cheese. Last, you add the tatertots over the top. The whole top layer is 100% tatertots.
Then bake according to the tatertot package instructions.
