Pleny shows dinners that use your things. Each one tells you what you already have and what is missing.
Missing something?
Tap to add the missing items to your shopping list. You do not have to shop for the whole recipe.
Use what goes bad first
Your pantry already knows what will go bad soon. Start with those items so nothing is thrown away.
Free plan
Free accounts can use this tool three times a day. Paid plans have no daily limit.
Why start with what you have?
The cheapest dinner is the one that uses food you already bought. It also stops food from going to waste. Many families throw away more than they realize, and a quick look in the fridge before shopping is the simplest fix.
What should you list?
Short names work best: eggs, spinach, rice, canned tomatoes. You do not need exact amounts. List the fresh food first, then the pantry basics.
Which foods turn into dinner easily?
| You have | Easy dinner |
|---|---|
| Eggs and any vegetables | Fried rice, frittata or scramble |
| Cooked rice | Fried rice or burritos |
| Canned beans and tomatoes | Chili, soup or bean tacos |
| Pasta and a jar of sauce | Baked pasta with whatever vegetables are left |
| Bread and cheese | Grilled cheese with a side of soup |
| Chicken and potatoes | Sheet pan dinner |
| Eggs and any vegetables | Fried rice, frittata or scramble |
| Cooked rice | Fried rice or burritos |
| Canned beans and tomatoes | Chili, soup or bean tacos |
| Pasta and a jar of sauce | Baked pasta with whatever vegetables are left |
What if you are missing one thing?
Look for a swap before you shop. Sour cream and plain yogurt trade places in most recipes. Milk with a spoon of lemon juice works as buttermilk. A dinner with one missing item is still a good dinner, and a short list is cheaper than a full one.
How do you use up food that is about to go bad?
Cook the oldest food first. Soft vegetables go into soups or sauces. Wilted greens go into eggs or pasta. Ripe fruit goes into smoothies or baking. Cooked leftovers should be eaten within 3 to 4 days or frozen.
How do you keep it from becoming a chore?
Pick one night a week as a use-it-up dinner. Everyone knows the rule: we eat what is here. It saves money, cuts waste and takes one decision off you.
What about food safety?
When in doubt, throw it out. Do not taste food to test it. If it smells off, has mold, or has been left out for more than 2 hours, it is not worth the risk.
