Pre heat a small sauté pan over medium-high heat. Add 1 teaspoon of oil to the pre heated pan. Add the diced peppers and garlic to the pan. Cook peppers and garlic until just crisp tender, 3 to 5 minutes. Season the pepper mixture to taste with salt and pepper and remove from the pan. Using the same pan, add the soy sauce and reduce by half. Once the soy sauce is reduced by half, remove it from the heat and set aside.
