Drain and press your tofu with a tofu press or by wrapping it in a linen towel and placing a heavy object on top for 30 minutes.
Heat oven to 400F.
Combine the soy sauce, maple syrup, and rice vinegar. Set aside.
When done pressing, cut the tofu into bite sized pieces and pour in just under half of the maple soy mixture.
Toss the tofu in the sauce, until it is covered. If you have time, marinate the tofu for 30 minutes.
Toss the tofu in cornstarch.
On a lined baking sheet, place the tofu in a single layer and bake for 20 minutes. Flip each tofu cube and bake for another 20 minutes.
If you are roasting your broccoli, you can roast them in the same oven on a separate tray for 20 minutes (I toss my broccoli in olive oil, salt, and garlic powder).
When done, toss the tofu with the rest of the maple soy sauce and assemble your meal prep containers by portioning out the tofu, broccoli, and rice into 4 airtight containers. Let cool before storing in the fridge for up to 4 days.
