Heat sesame oil in a large skillet over medium-high heat. Add onion to pan; sauté 3 minutes or until softened. Add garlic; sauté 30 seconds, stirring constantly. Add chicken; sauté 3 minutes or until chicken begins to brown.
Combine 3/4 cup water and the next 5 ingredients (through crushed red pepper), stirring with a whisk until sugar dissolves. Add water mixture to pan; bring to a boil. Add bell pepper and snow peas to pan; cook for 2 minutes or until vegetables are crisp-tender and sauce thickens. Sprinkle with nuts.
I thought the flavor of this was all heat and the garlic / ginger combo was just flat. The chicken probably should be spiced in some way (marinate?) before cooking. I won't make again though my husband did say he liked it. Boring and not worth adapting.
Served over brown rice and there was little flavor. We added salt, additional soy sauce (which was low sodium) and sambal oelek. I cut everything in half and it was enough to serve 3 people, so I imagine the whole recipe would serve 6 if served over rice.
