Dissolve the cornstarch in 2-3 tbsp of water in a small bowl or glass. Then add in the orange juice, maple syrup or agave, soy sauce, chili pepper, lime juice, and Jamaican Jerk seasoning. Whisk well.
Heat a frying pan to medium heat and then add in Crispy Seitan Bites. Pour sauce over and stir so that every piece is coated.
Reduce heat to medium and allow the sauce to simmer and thicken for 1 to 2 minutes.
At this step, you can either add the peppers and onions in or sautee them separately.
Ready to serve over rice, in a lettuce wrap, in a tortilla, or however you'd like! Add cilantro for a finishing touch.
