Start by preparing the marinade for the chicken. In a mixing bowl, combine 3 T soy sauce, 3 T fresh-squeezed lime juice, 2 T Sriracha Sauce, 1/4 cup sugar-free maple syrup, 3 T Golden Monkfruit Sweetener, 1 T minced garlic, and 1 tsp. sesame oil. Whisk until well combined.
Trim any fat or undesirable parts from the 3 large boneless, skinless chicken breasts. Cut each breast into chunks, about 8 pieces per breast, which will help with even cooking and flavor absorption.
In a Ziploc bag, add the chicken pieces along with 1/2 cup of the marinade. Seal the bag and shake it gently to ensure all pieces are coated. Marinate the chicken in the refrigerator for at least 6 to 8 hours, or even overnight if you have the time.
When you're ready to cook, preheat your oven to 425°F (218°C). This high heat will help achieve that beautiful caramelization on the chicken and green beans.
While the oven is heating, prepare your glaze. Take the remaining marinade and add 1/4 cup sugar-free orange marmalade and an additional 1 T soy sauce. Blend these ingredients together using a blender or food processor until smooth.
Next, prepare the green beans. Trim both ends of the 1 lb fresh green beans and cut them in half if they are too long. Toss the green beans with 1 to 2 tablespoons of the glaze to coat them lightly.
Once the oven is ready, take out a sheet pan and spray it lightly with non-stick spray. Remove the chicken from the marinade, letting it drain well, and arrange the green beans in a single layer on the hot sheet pan.
Place the chicken pieces among the green beans on the sheet pan, ensuring they are spaced out appropriately for even cooking.
Brush half of the remaining glaze over the chicken and green beans, ensuring everything is well coated.
Bake in the preheated oven for about 10 minutes. After this time, check to see if the chicken has released any water; if so, use a paper towel to blot it up.
Brush the chicken and beans with the remaining glaze and return them to the oven for an additional 10 minutes. This will deepen the flavors and create a lovely glaze.
Once cooked, remove from the oven and, if needed, blot any extra liquid again. Finally, sprinkle with 1 T toasted sesame seeds for that finishing touch and serve hot.
