Heat olive or avocado oil in a large nonstick skillet or wok over medium-high heat. Add the cubed tofu and cook for 4–5 minutes, flipping occasionally, until golden brown and slightly crispy on all sides.
1 cup tofu, 1 tbsp olive oil
Push tofu to one side of the pan. Add garlic and ginger to the cleared space, sautéing for 30 seconds until fragrant.
½ tsp garlic, ½ tsp ginger
Add the frozen stir-fry vegetables, edamame, and bell pepper to the pan. Stir everything together and cook for 4–5 minutes, or until veggies are hot and crisp-tender.
½ cup edamame, 1½ cups vegetable mix, ½ cup bell pepper
Stir in the cooked brown rice. Pour in the soy sauce, rice vinegar, and a pinch of red pepper flakes or black pepper, if using. Toss everything to combine, breaking up any rice clumps. Stir-fry for 2–3 minutes until rice is heated through and well coated.

Turn off the heat and drizzle in the toasted sesame oil. Stir briefly to distribute.
