Crock-pot Mongolian Beef

This was a goodie and so easy! Everyone in my family liked it, except the 4-year-old who doesn't like anything that's not Cheeto-based. I don't count her opinion anymore.

1 lb beef flank steak, sliced thinly across the grain
1 medium white onion (about 1 cup)
1/2 cup light soy sauce or 1/2 cup Braggs liquid aminos
1 cup chicken broth
1 tablespoon minced garlic
2 tablespoons hoisin sauce
1/4 cup dark brown sugar
1 tablespoon ground ginger or 1 inch piece fresh ginger grated
1/2-1 teaspoon red pepper flakes, to taste
1/4 cup cornstarch
1 cup cut scallion, in 1 . 5 inch pieces (green onions)
1/3 cup fruity white wine

1 Slice the flank steak thinly across the grain - the strips should be 2 to 3 inches long each; set aside.

2 Combine the onion, soy sauce, broth, garlic, hoisin, brown sugar, ginger, and pepper flakes, then put the mixture into the crock pot.

3 Put the cornstarch in a large Ziploc bag; add the sliced beef and toss well to coat. (It practically kills me to use up a gallon bag for such a simple task, but I did, and the food was worth it in the end.)

4 Add the coated beef into the crock pot, gently pushing it into the liquid to cover; pour the white wine over - do NOT stir.

5 Cook on low for 4 to 5 hours; an hour before you're going to serve, turn the crock pot to high, add the cut scallions, stir, and cook for an additional hour.

6 Stir, and serve over rice or noodles.
