Preheat the oven to 210°C / 410°F.
Dice squash into 1-2 inch pieces.
Cut broccoli and cauliflower florets from the stalk, removing any leaves. You may need to half or quarter some larger florets so that they are all of a similar size. If you only purchased florets you can skip this step.
Coat your marinaded tofu with some oil. If you want to, you can also drizzle some oil onto the vegetables as well.
Place your diced squash, broccoli & cauliflower florets, mini bell peppers and tofu in a single layer on a sheet pan.
Roast vegetables and tofu in the oven for 15 mins.
Then flip the tofu and roast for another 10 mins.
Take the vegetables out of the oven when it's cooked to your desired liking.
While vegetables and tofu roast, cut your avocado into slices and set aside.
