Tofu Broccoli Mushroom Stir Fry

First, make the sauce. Combine all the sauce ingredients in a mason jar. Add the lid and shake until well mixed and set aside. Do not add the sauce to the pan. If you don't have a mason jar you can also just whisk the ingredients in a bowl.
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add in the onions and broccoli and cook for 5 minutes, stirring occasionally.
Add in the other tablespoon of olive oil and the mushrooms to the broccoli and onions and continue to sauté for another 3 minutes.
Add in the tofu and cook for another minute, stirring gently.
Pour the stir fry sauce into the pan with the veggies. Cook 1-2 minutes, stirring occasionally, or until the sauce has thickened. Taste and add some salt and pepper if needed.
Serve over rice (optional). You can also optionally top with a sprinkling of sesame seeds or red pepper flakes for more spice. Once cooled, store any leftovers in an airtight container. It keeps in the fridge for up to 5 days.
