In a large skillet over medium, heat olive oil. Add onion and sauté for 3 minutes or just until onion begins to turn golden. Stir in corn and next 4 ingredients. Sauté 2 – 3 minutes or until veggies are crisp-tender. Remove from heat and stir in cilantro. (Can be served with Tostitos as a snack or hors d’oeuvre.)
