In a 12-inch nonstick skillet, heat the oil over medium-high heat. Add the curry powder; cook 1 minute, stirring constantly to prevent scorching and to develop the flavor. Stir in the garlic, bell peppers, onion, edamame, salt and 1/4 cup water (add water last so it doesn't spatter). Cook 2 minutes, stirring frequently and scraping bottom of skillet to mix curry powder with vegetables. Cover with lid; cook about 4 minutes longer or until vegetables are tender.
