Heat 2 teaspoons oil in a large wok or skillet over medium-high. Add chicken; cook, stirring often, until browned and done, 5 to 6 minutes. Remove chicken. Add remaining 1 teaspoon oil, pepper, green beans, snap peas, shallot, and garlic. Cook until crisp-tender, 5 to 7 minutes. Whisk together fish and soy sauces, honey, sambal oelek, 1 teaspoon water, and cornstarch in a small bowl. Add to wok with chicken, stirring to coat chicken and veggies; cook until sauce thickens, about 2 minutes. Remove from heat; add peanuts and scallions.
