Simple Beef Stir Fry

Have you ever had a craving for something, but there were no places around that cooked that particular food or dish?

    Well that is basically the answer for just about every craving I ever have. Living in a small town, we don't have much. Yes, we have a McD's, Sonic(yuck!), and Denny's(double yuck!),a few pizza places, an itty-bitty teeny-tiny italian restraunt and a Soulman's BBQ, but that's it. No sushi, no Chick-fa-la, no Starbucks, no  french bistros, no amazing mexican restraunts. NaDa! They are all in the neighboring towns. (we actually have a small chinese place that opened recently, but the "food" is mostly sauce, not meat or veg; so we only went once.)
    Recently, I have been wanting Chinese food. Stir fry to be exact. Beef and veggie stir fry to be even more exact. Well after looking online for several different recipes, I did what I usually do. I combined a few recipes and made it my own by changing some things.

Mix together everything for the sauce and cut the onion and pepper(s) 

I actually had some assorted peppers already sliced and frozen; so I measured what I thought would equal 1 pepper
