All the guys in my life love this sandwich recipe:
The bread you use in this matters; get a really nice fresh French bread, or good-quality grinder (sub) rolls, fresh store-baked are good.
1 green bell pepper, sliced in long pieces 1/4" wide
1/4 of a red bell pepper, same
1 large onion, minced
1 clove garlic crushed and minced
1 lb. package keilbasa, either turkey or regular
In heavy non-stick skillet slowly saute veggies in 1/2 cup high-quality olive oil over medium-low heat about 15 minutes, stirring occasionally. Slice up keilbasa, slices no more than 1/4" inch thick, add to veggies, stir up. Heat goes up to medium. Cook 10 minutes, stirring occasionally. Spoon hot into sandwiches, serve immediately.
You can vary the saute any way you prefer, eliminating garlic, adding minced peppers of other types, etc. We like these without cheese on top but you can do that too.
Happy Chinese New Year!
