Asian Beef with Mushrooms and Snow Peas

Sauce ingredients:
1/2 c. tamari or low-sodium soy sauce [I used low-sodium tamari sauce.]
5 TBSP brown sugar
6 garlic cloves, minced
1/2 tsp ginger
2 tsp rice vinegar

4 TBSP olive oil
10 oz mushrooms, thinly slice [I used a large package of sliced baby bellas.]
10 oz. snow peas
1 lb thinly sliced beef

Combine all the sauce ingredients in a bowl then set aside.

Heat 2 TBSP oil in a large skillet, then cook the mushrooms on high, turning occasionally, until they start to brown.  Add in the snow peas for the final few minutes.  Remove to a bowl.

In the same skillet, add 2 TBSP oil to the skillet, then immediately add sliced meat, browning both sides.  (You may need to cook in two batches.) 

Return all the cooked beef slices, mushrooms, and snow peas to the skillet, then add the Asian sauce.  Stir to combine and cook on high heat for at least 1 minute.  Turn off heat and cover with skillet lid.
