Peel and cube the potatoes, boil until tender, about 10 minutes, drain.
While the potatoes are cooking, prep the sausage links by slicing half the sausage, bell pepper, pimento, and onion. (I used chicken cocktail sausages, yellow bell pepper, and omitted the pimento.)
Cook onion in the melted butter until soft but not browned.
Stir in the soup and milk, heat through. (I used condensed chicken mushroom soup as variant.)
Preheat you oven to 180° C (350° F), get out a 1½ quart casserole. (I did double the recipe so I used a 3 quart casserole for this.)
To the casserole, add the drained potatoes, bell pepper, pimento, and the sliced sausage, toss together.
Pour soup mixture over the top of the potatoes.
Top with the shredded cheese.
Arrange remaining sausage links on top.
Bake for 30 minutes.
Serve and enjoy.
