To efficiently make a burrito bowl, the order of operations matters. Start with anything that needs to be roasted, like cauliflower. Prepare and place into oven before starting anything else. Usually takes 40-50 minutes depending on the veggie. Then prepare and cook rice while the cauliflower roasts. Rice can take 20-40 minutes depending on the kind (brown takes longer). Now prepare and saute "harder" veggies like onion and bell pepper - usually takes 5-15 minutes to cook. Prepare sauteed corn or "soft" veggies. Corn off the cob is a softer veggie and only takes 5-10 minutes. Lastly, prepare any salsa or guac. If not serving right away, add plenty of lime juice to guac to keep from browning. Set up your burrito bowl bar (or meal prep containers) and enjoy!
