Heat olive oil in a large skillet over medium heat; add the asparagus and red onion and saute until the onion begins to soften, about 5 minutes. Stir in the bell pepper and continue cooking, stirring occasionally, for 5 minutes. Remove from heat, add the vinegar and cheese; toss until mixed and serve.
