Chop the vegetables, mince garlic and grate the ginger, prepare your other ingredients as well, so that you have everything ready.
Stir-fry the broccoli and green beans in olive oil at medium high. I actually covered mine in the beginning for 1-2 minutes, so that the broccoli can cook a bit and because I was using frozen green beans. If you do cover the vegetables, keep this short, a minute or two and no more, so that the vegetables don't get mushy.
Add the red pepper and stir-fry for 3-4 more minutes.
Stir in the the tamari sauce. And then add the shrimp, stirring for 2-3 minutes
Add in the minced garlic, ginger, red pepper flakes and scallions. Stir for another 2-3 minutes. At this point your shrimp should have turned pink and the broccoli would be ready.
Serve immediately!
