Preheat the cast iron over high heat. On my stove, I bring it up to about 8, but stovetops vary. In the meantime, mix together the sauce ingredients and set aside.
Have at the ready a baking pan or mixing bowl to place the ingredients as they finish cooking. I like to use a 9×13 pan so that there’s plenty of room and things aren’t sitting on top of each other and steaming.
Once pan is good and hot, apply a thin layer of olive oil. Add the cubed tofu and sprinkle with a pinch of salt and fresh black pepper. The ingredients should immediately sizzle when they hot the pan, otherwise, turn the heat up. Cook for about 7 minutes, tossing often and spraying with oil as necessary, until it’s nicely browned, like so:
All sides don’t have to be evenly browned, just as long as a few of them are, you’re good to go.
Transfer tofu to the baking pan or bowl, and proceed with the broccoli. Apply a thin layer of oil, toss in broccoli, add a pinch of salt and fresh black pepper. Cook until broccoli is charred and bright green, about 5 minutes. Cover the pan between tosses, so that it cooks faster. Transfer to the pan with the tofu.
Now proceed with the onion and peppers. Apply a thin layer of oil, and toss in the onions and peppers. Spinkle with a pinch of salt and fresh black pepper. Cook for about 3 minutes, it should be charred but still crisp. Transfer to the pan with the tofu. Now we’ll finish it off with the sauce.
Add the garlic, ginger and red pepper flakes to the cast iron pan and drizzle with a little oil and saute until fragrant (about a minute) being careful not to burn. Add the sauce and mix together until heated through and bubbly, about 2 minutes.
Now, add back all the veggies and the tofu and toss to coat. Taste for salt and seasoning.
Serve over quinoa or brown rice, top with avocado, peanut and basil and serve hot!
