Preheat oven to 400 and start cooking your rice
While the rice is cooking, chop cauliflower into florets, and add to a large bowl and toss with olive oil and flour.
Line a baking sheet with parchment paper, add the seasonal vegetables to the baking sheet, and bake for 20-25 minutes, until cauliflower is tender-crisp but not soggy.
While that is cooking, whisk together the sweet and sour sauce by adding all ingredients to a small bowl and mixing with a fork.
Once the cauliflower is done baking, remove from the oven and toss with the sauce to lightly coat.
To assemble, divide jasmine rice and cauliflower/veggie mixture between meal prep containers and top with diced scallions. That's it!
