Eating well during a hectic week usually fails because we have no plan, not because we lack willpower. A simple Sunday meal-prep routine solves that by making healthy lunches the easiest option.

• Pick a template: Use the same formula every week, like protein + grain + roasted vegetables, to keep shopping and cooking simple.
• Batch cook smartly: Roast two trays of vegetables and cook one large batch of grains or legumes to mix and match across five containers.
• Choose sturdy ingredients: Hearty greens, roasted roots, and grains hold up for days, while delicate leaves and sauces should be added fresh.
• Store correctly: Use airtight glass containers and refrigerate within two hours; most prepped meals stay fresh for three to four days.
• Freeze for variety: Make double batches of soups or curries and freeze them so you never face a boring or empty fridge day.

An hour of prep on Sunday saves you money, stress, and hundreds of calories in takeout every single week.
