4 ounces shredded low-fat cheddar or mozzarella cheese
1 large avocado, peeled and sliced, for garnish
Bring large pot of lightly salted water to a boil, and cook tortellini according to package directions. Drain and rinse.
Meanwhile, heat 1 tablespoon oil in large skillet over medium heat. Saute garlic 30 seconds, and add tomatoes and chili powder. Cook 5 to 8 minutes; remove from skillet.
Reheat skillet with remaining 1 tablespoon oil, and add mushrooms and soy "meat." Saute 2 to 3 minutes, or until mushrooms begin to soften. Stir in tomatoes and cheese; cook, stirring often, 5 minutes more.
Spoon equal portions of pasta onto plates; top with "meat" sauce, and garnish with avocado slices.
