Add chopped peppers and mushrooms to a pan. Heat on the stove on medium heat for 5-10 minutes. Stir occasionally and add a bit of water if needed to prevent sticking.
While the vegetables are cooking, drain your tofu and mash it up in a bowl. I just squeeze it with my hands. You could also use a fork or masher.
Add all remaining ingredients to the bowl with the tofu and mix it all together.
When you are done heating the vegetables for 5-10 minutes, add the tofu mix to the pan and heat for about 5 additional minutes. Mix everything in the pan while it cooks. If sticking occurs, add a bit more plant milk or water.
Remove the pan from heat when your tofu scramble is finished. Top with avocado and more scallions if desired.
Notes
If you can't find a package of tofu that can easily be broken into a block of 175 grams, you should use a food scale to ensure that you have the correct amount of tofu for this recipe. I buy a block that is 350 grams and simply cut it in half.
