Combine all Country Beef Breakfast Sausage ingredients in large bowl, mixing lightly but thoroughly. Heat large nonstick skillet over medium high heat until hot. Add sausage mixture; cook 8 to 10 minutes, breaking into 1/2-inch crumbles and stirring occasionally.

Set aside 2 cups sausage mixture in large bowl; reserve remaining sausage for another use. Add mushrooms and onions to same skillet sprayed with cooking spray over medium heat; cook 5 to 7 minutes or until vegetables are tender, stirring occasionally. Add spinach to skillet; stir to wilt. Add vegetable mixture to beef; set aside 20 to 25 minutes or until mixture is cooled completely, stirring occasionally. Stir in cheese.

Preheat oven to 425°F. Unroll pizza dough on flat surface; pat or roll dough evenly to 14 x 10-inch rectangle, pinching together any tears, if necessary. Spread sausage mixture on dough, leaving 1/2 inch border on short side furthest from you. Starting at closest short end, roll up jelly-roll style, pinching to close. Slice dough into 8 pieces using serrated knife and careful sawing motion; place cut-side-up on greased baking sheet.

Bake in 425°F oven 18 to 20 minutes or until golden brown. Remove buns to cooling rack. While still warm, drizzle with melted jalapeño pepper jelly, if desired.

NOTE: To warm jelly, place jelly in 1 cup glass measure. Microwave, uncovered, on HIGH 45 to 60 seconds or until melted, stirring once. Let stand 30 seconds.
