Stir fry veggies: Add about half tablespoon oil to
large skillet over medium heat. Add diced onion and chopped bell pepper stirring frequently until onion is fragrant – about 3 minutes. Add in sliced mushrooms and continue stirring for another 2-3 minutes until soft. You can also add kale here and cook down about 2 minutes or keep raw. Transfer veggies to plate; set aside.
