Brown sausage in hot oil in a skillet over medium high heat. Do not try to cook through, brown quickly. Drain on paper towels. Place sausage into crockpot.
Pour salsa over sausage and mix to cover well. Cook on high for 4 to 5 hours. While sausage cooks, prepare rolls.
Using sharp narrow bladed knife, cut about 1 inch from the end of each roll. With your knife, begin to remove the soft bread carefully from the inside of roll. Do not pierce the end or the sides of the roll.
When ready to serve, carefully insert a link of sausage into end of roll and push until completely inserted. Serve immediately. Makes 12 servings. Enjoy!
