如果您厌倦了扔掉枯萎的农产品、为最后一刻的外卖支付过高的费用以及每周去三次杂货店，那么您并不孤单。据 ReFED 和 USDA 估计，美国家庭平均每年扔掉价值约 1,300 至 1,800 美元的食物。但使用可重复购物系统的家庭——每周一次的旅行、计划好的菜单和库存充足的食品储藏室——持续减少支出和浪费。
下面详细介绍了如何逐步构建该系统。无需优惠券。

如何购物一次并养活家人一整周
The one-trip system
- Plan every dinner before you write a single item on your list
- Check the pantry first — buy only what you're actually out of
- Organize the list by store aisle so you don't backtrack
- Shop the same day every week — habit beats willpower
What drives up the bill
- Walking into a store without a plan — impulse buys add 15–20% to every trip
- Multiple mid-week runs for 'just one thing' — each one triggers unplanned purchases
- Buying pre-cut produce, pre-marinated meats, and single-serve snacks at 2–3× the unit price
- Ignoring the pantry and buying duplicates of what you already have
四步购物系统
每周都使用这个。总共需要 25 分钟，比任何优惠券都节省更多。
Step 1: Plan your dinners
Pick 5–7 dinners for the week. Write down every ingredient you need. That's your starting list.
Step 2: Audit the kitchen
Open every cabinet, the fridge, and the freezer. Cross off anything you already have.
Step 3: Group by store section
Sort the final list by produce, dairy, meat, pantry, frozen — one pass through the store.
Step 4: Top off staples
After meal-specific items, add things running low: oil, soy sauce, flour, butter, salt.

White Bean and Tomato Soup
Ingredients
Aromatics
- 2 tbspolive oil
- 3garlic cloves(minced)
- 1 sprigfresh rosemary(or 1 tsp dried)
Canned goods (the pantry stars)
- 2 cans (14 oz each)white beans (cannellini or great northern)(drained and rinsed)
- 1 can (28 oz)crushed tomatoes
- 2 cupschicken or vegetable broth
To finish
- Salt and pepper to taste
- Parmesan rind(optional, adds depth)
- Crusty bread(for serving)
Steps
- 1
Sauté the aromatics
Heat olive oil in a large pot or Dutch oven over medium heat. Add minced garlic and the rosemary sprig. Cook for 1–2 minutes, stirring constantly, until the garlic is fragrant but hasn't browned.
- 2
Add the canned ingredients
Pour in the drained white beans, crushed tomatoes, and broth. Drop in the parmesan rind if you're using one. Season with a generous pinch of salt and a few cracks of black pepper.
- 3
Simmer until the flavors meld
Bring to a gentle simmer, then reduce the heat to medium-low. Let it bubble softly for 20 minutes, stirring every 5 minutes or so. The soup will thicken slightly as it cooks.
- 4
Finish and serve
Fish out the rosemary sprig and the parmesan rind (if used). For a creamier texture, mash about a quarter of the beans against the side of the pot with a wooden spoon. Ladle into bowls and serve with crusty bread.
Notes
- Any white bean works here: cannellini, great northern, or navy beans. Different beans change the texture but not the flavor.
- Keep parmesan rinds in a bag in the freezer. Drop one into any tomato soup, stew, or braise — it adds umami without adding salt.
- The soup keeps in the fridge for 5 days and freezes beautifully for 3 months. Double the recipe if you want backup meals.
- For extra nutrition: stir in a handful of fresh spinach or chopped kale during the last 3 minutes of simmering.
- Turn leftovers into lunch: blend the soup smooth, pack it in a thermos, and send it to school or work with crusty bread on the side.
