Beef & Cream Cheese Stir-Fry

Tonight I tried a different sauce recipe for a beef stir-fry, and both my husband and I liked it. Basically, here's what I did:

Ingredients
2-3 tbsp vegetable oil
1 large onion, sliced
2 large garlic cloves, diced
10 mushrooms, sliced
2 lbs frozen green beans (we buy them in a 1kg bag)
1 lb stewing beef, diced into small pieces (to make our meat last longer, we only use 0.5 lb of meat per main dish)
3 tbsp brown sugar
1 tbsp soy sauce
2 tsp apple cider vinegar
0.5 brick of cream cheese
0.5 cup milk
salt & pepper

Cooking Instructions
- steam green beans in a steamer or pot
- in a wok, stir-fry beef and onions together in vegetable oil
- add sugar, soy sauce, and vinegar
- when the meat is cooked, add garlic and mushrooms to the wok and simmer on low
- when green beans are finished add them to the wok
- meanwhile, beat together milk and cream cheese, then add to meat and veggies in the wok
- salt and pepper to taste
- serve over jasmine rice (I'm sure it would taste great on any kind of rice, and might even be good over pasta too)
