Cook rice slightly underdone so reheating keeps texture. Cool quickly and portion into airtight containers with proteins (grilled chicken, tofu), cooked veggies, and sauces stored separately if possible. Use sturdy veggies (roasted sweet potato, broccoli) that reheat well.
Reheat in microwave with a splash of water to restore steam. Keep refrigerated up to 4 days. For variety, swap toppings and sauces each day.
