In a small bowl mix together the ingredients for the Cooking Sauce.
Add the diced chicken in a small bowl and mix with 2 tablespoons of the Cooking Sauce. Reserve the rest of the sauce. Marinate the chicken for 30-60 minutes.
Preheat flat top to medium-high heat (about 400 degrees). If using a a Cooking Steel we find it best to set up the grill to have a hot side and a cooler side, so you can move items that are done cooking, or cooking too fast to the cooler side of the grill. If using a Blackstone or similar, set it to 400 degrees.
Add a couple tablespoons of cooking oil to the flat top and give it a couple minutes to heat up. We like to use peanut oil for this recipe.
Once the oil is heated, add the diced onion, garlic, carrots, and green onion and cook for about 2 minutes, stirring frequently.
Add the marinated, diced chicken to a different area of the grill and cook for about 2 minutes, stirring frequently until evenly browned, then mix in with the vegetables and add in the peas. Move to the cooler portion of the grill, or remove to a bowl if necessary.
Add a little more oil to the flat top if needed, then add the chilled cooked rice. (Note: It is helpful to break up the rice before adding it to the grill to avoid large clumps. Also, make certain you are using chilled rice. Warm, fresh rice will not fry correctly.)
Cook the rice for about 2 minutes, stirring frequently, then mix together with the veggies and chicken. Mix in the reserved cooking sauce and mix to combine.
While the rice is heating through with the cooking sauce, add the beaten egg to a separate area of the flat top. When the bottom of the eggs are set, stir them around and break apart. Once completely cooked, mix in with the rest of the fried rice.
Serve warm.
