In a large skillet, cook and crumble sausage over medium-high heat until no longer pink, 5-7 minutes; drain. Add pepper and green onion; cook and stir 2 minutes. Transfer to a bowl; cool 10 minutes. Stir in cream cheese until blended; cool completely.

Unroll 1 can of crescent dough and separate into 4 rectangles; pinch perforations to seal. Press each rectangle to 6x4-1/2 in.; spread each with 1/3 cup filling to within 1/4 in. of edges. Roll up jelly-roll style, starting with a short side; pinch seam to seal. Roll gently to make logs smooth. Place on a waxed paper-lined baking sheet, seam side down. Repeat with remaining crescent dough. Freeze, covered, until firm, about 1 hour.

Preheat oven to 350°. Cut each log into 10 slices. Bake on parchment-lined baking sheets until golden brown, 15-18 minutes. Serve warm.
