Snow Peas & Beef Stir-Fry

E. helped me make this new recipe last evening for supper.  My guys thought it a little bland, but I loved it!

Snow Peas & Beef Stir-Fry

1/2 C. reduced-sodium soy sauce
1/2 C. water
2 tabl. cornstarch
2 tsp. sugar (or Splenda)
2 tabl. canola oil, divided
1/2 tsp. garlic powder
1 sirloin steak (1 1/2 lbs.), thinly sliced
1 medium onion, cut into thin wedges
8 oz. fresh snow peas
Hot cooked rice

In a small bowl, whisk soy sauce, water, cornstarch and sugar.  Transfer 1/4 C. mixture to a large bowl; stir in 1 tabl. oil and garlic powder.  Add beef; toss to coat.  Let beef mixture stand for 15 minutes.  Heat a large skillet over medium-high heat.  Add half of the beef mixture; stir-fry for several minutes until no longer pink.  Remove from pan; repeat with remaining beef.  In same pan, heat remaining oil over medium-high heat until hot.  Add onion; cook and stir until tender.  Add snow peas; cook 2-3 minutes longer or until crisp-tender.  Stir remaining soy sauce mixture and add to pan.  Bring to a boil; cook and stir 1-2 minutes or until sauce is thickened.  Return beef to pan; heat through.  Serve with rice.
