In a large pan (make sure it’s oven safe) heat the olive oil over medium heat. Once hot, add the chicken in one layer. Cook for three minutes on one side until nicely browned and then flip and cook for another three minutes on the other side.
Meanwhile, prepare the veggies until just tender crisp. The easiest way to do this is by quickly placing in boiling water for 2-4 minutes until bright in color and just tender. You can also microwave for 4-5 minutes until just tender. Make sure to not overcook your vegetables.
