Prepare white or brown rice according to package directions, or follow my recipe for Ninja Foodi Rice. Prepare the vegetables, by washing and chopping them. Dice the onion, and mince the garlic. Peel and chop the carrots into strips. Chop the red pepper into strips. Cut the broccoli heads. Roughly chop the bok chop, and slice the mushrooms if not already sliced.
Add a tablespoon of sesame oil or olive oil to a large sauté pan over medium heat. Add the chopped onion. Cook for about 3 minutes until softened. Then add the garlic and the ginger paste. Stir to combine, and cook for an additional minute.
Add in the sliced carrots and the red bell pepper. Cook for 2-3 minutes. Then add in the broccoli, mushrooms, baby corn, and snow peas. Cover and steam for 5 minutes.
While the vegetables are steaming, whisk together the vegetable stock, soy sauce, sesame oil, rice vinegar, maple syrup, garlic, and cornstarch. Set aside.
Remove the lid from the steaming vegetables. Add in the chopped bok choy, and pour the sauce over the vegetables. Stir to combine. Cover and allow to steam another 2-3 minutes. The sauce should thicken and coat the vegetables.
Remove the pan from the heat. The vegetables should be tender but have a bit of crunch. Serve immediately with brown rice, or your choice of noodles, rice, or quinoa.
