Whisk together all ingredients for the sauce, set aside.
Toss the pork with the cornstarch, salt and pepper, until fully coated. Set aside.
Heat a sauté pan over medium high heat. Add one tablespoon of oil. Add the bell pepper and snap peas. Cook, stirring often, until starting to brown and blister, 4-5 minutes. Remove from pan and set aside..
Add the second tablespoon of oil to the pan. You may need to adjust heat as you cook, it should be hot but turn the pan down if the bottom starts to burn while browning pork. Add the pork, but do not overcrowd the pan. Cook in two batches if necessary. Cook pork 3-4 minutes per side, until cooked through.
Add the vegetables back to the pan with the pork. Pour in the sauce. Stir, scraping up and browned bits on the bottom of the pan. Cook for 2-3 minutes, until everything is fully coated and the sauce has thickened. Garnish with sesame seeds and serve over rice if desired.
Notes
Want to add more vegetables? Feel free to change them up! Just keep in mind that different vegetables will have different cook times, so you will need to be aware of when you add them to make sure they all end up cooked at the same time.Substitutions:If you don't have rice vinegar apple cider vinegar or white wine vinegar will work in a pinch.If you don't have sambal oelek, try chili garlic sauce, sriracha or a pinch of red pepper flakes.
