Frozen salmon (fish).

Preheat the oven to 425

Put a salmon fillet on a baking tray with some foil for easy clean up

Sauce and/or season (salt, pepper, olive oil minimum)

Bake for about 20min until the fish is flaky and cooked.

This can be applied to almost any flash frozen fish, requires no preparation, cleans up easy, and scales up to multiple people without scaling the work.

Want sides with this? Microwaved Green beans with olive oil, salt, and pepper. Minute/microwave rice.
