Drizzle 1 or 2 Tbsp of olive oil into a 10" skillet. Heat skillet before putting in the sausage.
When skillet is hot, cook the rope sausage on medium high heat until some of the pieces are browned.
Stir in 1/2 cup water, stir around on bottom to pick up all that wonderful flavor; add the potatoes and green beans. Add salt, pepper and garlic to taste.
Give it a good stir, and then cover and simmer until potatoes are fork tender, approximately 20 min. Stir once or twice while simmering.
