The vegan quinoa bowls keep best if the components are stored separately in the fridge, then put together on the day or the night before. Bento style boxes are perfect for meal prep as they keep the components packed separately, but together at the same time. If you would rather just pack everything together ready for the week, my only suggestion would be to store the peanut sauce in a little pot separately, then pour it over before eating. This will keep it nice and fresh and stop it from soaking into your food and making it soggy.
