1Slice the chicken breast into thin strips.
In a small bowl, mix the soy sauce, chili garlic sauce, cornstarch, and black pepper. Set aside.
Slice the bananas into thick rounds. Cut the red bell pepper into thin strips and trim the snap peas.
Heat the olive oil in a large skillet or wok over medium-high heat.
Add the chicken strips and stir-fry for 4-5 minutes until cooked through and lightly browned. Remove the chicken from the pan and set aside.
In the same pan, add the red bell pepper and snap peas. Stir-fry for 2-3 minutes until just tender.
Return the chicken to the pan. Pour in the sauce mixture and stir well to coat everything evenly. Cook for 1-2 minutes until the sauce thickens.
Gently fold in the banana slices and cook for another 1 minute, just until heated through.
Serve immediately, garnished with extra black pepper if desired.
