In the portions written below, protein is about 26–36 g, calories about 310–520, and sodium about 200–280 mg. Those are rounded kitchen estimates before extra cheese, bread, or a heavy pour of sauce.
Safely cooked leftovers generally keep 3–4 days at 40°F or below. After that, it should already have been frozen or eaten.
How to run it
- Start with herb egg salad. Plan on about 15 minutes. Cover the eggs with water, bring to a boil, then cover and sit 10 minutes off the heat. Cool them in cold water.
- Next, chicken and farro lunch jars. This is a packing pattern more than a delicate recipe. The mistake is mixing the dressing in on Sunday.
- Keep rice, beans, and eggs for the meal that needs to feel different. Cook and eat. Rice and beans can sit in the fridge 4 days; cook the eggs when you eat.
- Cool anything you will not eat right away within two hours. For rice, beans, and eggs: Cook and eat. Rice and beans can sit in the fridge 4 days; cook the eggs when you eat.

Details that matter
- If one person wants more food, add rice, potatoes, or an egg. Do not cook two entirely different dinners.
- Cook a full recipe and freeze half before you are bored of it. Future-you is a different customer.
- Eggs, a baked potato, a yogurt jar, and a can of no-salt tuna are the emergency shelf.
Easy mistakes
Letting produce liquefy because the recipe only needed half an onion
The other half goes into eggs, soup, or the freezer. Write it on the meal plan so it has a job.
Shopping hungry for one person with a cart built for four
A short list beats a 'stock up' trip you cannot finish.
