I hate to waste food. It pains me every time I drop a half-bag of wilted celery into the trash or dump a container of mold-covered spaghetti down the garbage disposal. For years, the National Resources Defense Council has reported that nearly 40 percent of the food produced in the U.S. gets trashed, much of which winds up in landfills where it rots and emits greenhouse gasses, wreaking havoc on the environment. Yet many people in this country are malnourished.

A growing number of cookbooks I see address the issue head-on, and I welcome all tips for helping me shrink my personal carbon footprint.

The latest to catch my attention is “Perfectly Good Food: A Totally Achievable Zero Waste Approach to Home Cooking” by Margaret Li and Irene Li (Norton, $28). The sisters co-founded with their brother, Andy, an award-winning food truck and restaurant that’s now Mei Mei Dumplings in Boston; their previous book, “Double Awesome Chinese Food,” is among my keepers. Margaret, who now lives in Glasgow, Scotland, and Irene also run Food Waste Feast, an online project to help home cooks avoid waste.

“Perfectly Good Food” is an illustrated softcover that is less about rigid ingredient lists and more about strategies for smart shopping and kitchen set-up. With recipe names like Kitchen Scrap Stock, Eat-Your-Leftovers Pot Pie, Anything-You-Like Galette, Pick-Your-Protein Salad, and Choose-Your-Own-Adventure Vegetable Paella, you get the picture.

The chapters lean heaviest on maximizing produce, with a smaller section on stretching proteins and dairy. Within each are tips using up every last scrap: sauteing leek tops for a pasta topping, frying up leftover rice into fritters, turning half a carrot into an instant pickle, pureeing wilted lettuce into soup, mixing up mushy berries into sangria. Freezing and storage tips abound, as does advice on how to tell if an onion with green sprouts is still safe to eat, and whether a cucumber that’s gone limp is salvageable (Stir-Fried Pork with Cucumber and Zucchini is your answer.)

To the Li sisters, devising a fridge cleanout meal is more than an exercise in virtue. It’s also a fun game of puzzle-solving — “and then we get to eat it! Much tastier than the Sunday crossword.”
