I got this recipe off of Pioneer Woman. I changed a few things. I highly recommend her site. I have made a lot of her recipes and every single one has been great. It is not a paleo site though. I repeat it is not a paleo site.
1½ pound Flank Steak, Trimmed Of Fat And Sliced Very Thin Against The Grain
½ cups Low Sodium Soy Sauce
3 Tablespoons Sherry (Not Paleo)
2 Tablespoons Brown Sugar (Not Paleo)
2 Tablespoons Cornstarch (Not Paleo)
1 Tablespoon Minced Fresh Ginger
8 ounces, weight Fresh Asparagus
5 whole Scallions, Cut Into Haf-inch Pieces On The Diagonal
3 Tablespoons Olive Oil
Crushed Red Pepper, For Sprinkling
In a bowl, mix together soy sauce, sherry, brown sugar, cornstarch, and ginger. Add sliced meat to bowl and toss with hands. Set aside.
Heat oil in a heavy skillet (iron is best) or wok over high heat. Add asparagus and stir until cooked. Remove to a separate plate. Set aside.
Allow pan to get very hot again. With tongs, add half the meat mixture, leaving most of the marinade still in the bowl. Add half the scallions. Spread out meat as you add it to pan, but do not stir for a good minute. (You want the meat to get as brown as possible in as short amount a time as possible.) Turn meat to the other side and cook for another 30 seconds. Remove to a clean plate.
Repeat with other half of meat, allowing pan to get very hot again first. After turning it, add the first plateful of meat, the rest of the marinade, and the asparagus. Stir over high heat for 30 seconds, then turn off heat. Check seasonings and add salt only if it needs it. Mixture will thicken as it sits.
Serve immediately. Sprinkle crushed red pepper over the top to give it some spice.
