Easy and delicious, and only 3-4 of the ingredients are perishables you need to get. The rest are pantry items:
* ~2lb sirloin (flank if you have money to burn)
* Some soy sauce
* Sesame oil
* Onion powder
* Garlic powder
* 2 white onions
* Peppers of some kind (I like shishito for this, and something really spicy if I’m not cooking it for my family)
* Scallions (if you want, there’s already onions)
* Baking soda
* Corn starch
* Beef bouillon paste
Cut the streak in thin slices across the grain, think stir fry size. Toss in a bowl with onion powder, garlic powder, soy sauce, baking powder, and sesame oil. I don’t measure when I cook, but I’d guess maybe 2 tbsp of onion powder, 3 tsp garlic powder, 3 tbsp soy sauce, 1 tsp sesame oil, 3 tsp baking powder. Eyeball it and toss well to coat the meat evenly. If it seems like too much, do less. You can always add stuff later.
Let it marinate for a while, 1-4 hours usually. I do it a few hours before I want to cook, it cooks fast. Meanwhile chop the onions and peppers.
Heat some oil in a Dutch oven or other large pot. When it’s hot put the beef in and brown it for a few minutes.
Add the onions and peppers and toss for a few minutes and let them cook.
Next prepare two cups of the beef bouillon paste according to its directions. Add it to the pot and mix everything.
Finally, add about 3 tsp of cornstarch to a small bowl and about an equal amount of water. Mix it until there are no more lumps and before it settles out again add it to the pot and let it simmer a little longer, or until the sauce is almost thick enough. It’ll thicken more as it cools.
Serve over rice or whatever you want.
