Clean and cut the chicken tenderloin and seafood into bite-sized pieces.
Cut vegetables such as bell peppers and onions into pieces suitable for eating.
Heat cooking oil in a pan and stir-fry the chicken tenderloin first.
When the chicken is about halfway cooked, add the seafood and vegetables and stir-fry together.
Season with salt, pepper, soy sauce, or other seasonings to taste.
Once all ingredients are fully cooked, remove from heat and serve on a plate.
