One of the great things about Asian food is that there are hundreds of quick sit-fry dishes.
As long as you have the following few ingredients handy – garlic, shallots/onions, scallions, and ginger etc.- you are pretty much guaranteed to deliver a satisfying meal.
Today’s recipe is one of the few that I serve regularly in my household.
There are two ways to prepare it:
1. Pre-slice the steak (cut thinly across the grain) and marinate overnight & a quick stir-fry with the rest of the ingredients (pineapple & bell peppers) when you are ready to eat. OR
2. Have the entire dish ready and stored in an airtight container. Re-heat in a microwave and scoop as much as you want throughout the week.
There are pros and cons to each method so it totally depends on your preferences.
I opted for method 2 this time because my time is usually very limited during the work week and cooking is the last thing I want to think of at the end of a day.
If you also opt for method 2, the trick is to saute the bell pepper and pineapple chunks for only a few seconds so when you reheat in a microwave, the veggies won’t turn mushy.
Flank steak is low-cost and delicious. As long as you follow the steps below, I guarantee this dish will become one of your favorites !
