Stir fry black bean beef with spinach and edamame

This turned out really nicely - probably one of my favourite meals so far. Easy to cook, too; it follows my basic method for pretty much all of my stir-frys:

1. Chop up a thumb of ginger, 2 cloves of garlic and 3-4 spring onions and heat up a wok.
2. Stick some olive oil in the wok along with the above ingredients. Cook them for around 2 minutes just until they start to get softer. 
3. Put some spinach in a bowl with around 3 tbs of water, cover the bowl and put it in the microwave for 3 minutes. At the same time start boiling/steaming the edamame, however it says on the packet.
4. Chuck in your meat. If you're cooking chicken, cook until it's sealed (no more pink anywhere) and then put in your stir fry sauce of choice. With beef just add the sauce after a few minutes. Add the spinach and edamame towards the end and stir everything around together.
5. That's pretty much it. You might want to marinade your meat in your sauce of choice for about an hour or so before you cook your stir-fry.
