This is a recipe my mother always made as a kid, and I loved it. Quick and easy too.
For two:
3/4 of a smoked sausage (of the normal packed smoked sausage where it's one big long piece in plastic)
1 Can of green-beans (cut) (better with canned vs. fresh)
Salt and Pepper to taste. I prefer fresh ground pepper for this meal.

Throw all ingredients in a pan and heat until warm. Do not boil. Drain the juice. Serve. Easy for packing too. Just heat up in the microwave.

My mom used to add cabbage that she'd cook down, but I'm not a fan. She'd also used to serve this with a side of sour kraut.
