The short answer
Stretch a small shopping list across bean-rice bowls, tomato-lentil soup and chickpea toast. Compare unit prices and use frozen vegetables or store-brand canned legumes; exact savings depend on local prices.
Three lunches from shared staples
Cook rice and lentils for the first two lunches. Day 1: serve rice with beans and frozen mixed vegetables. Day 2: simmer lentils with canned tomatoes. Day 3: mash canned chickpeas with lemon and serve on wholegrain toast. Use olive oil as available.
Make cost visible before choosing a plan
Buy rice, lentils, beans, chickpeas, canned tomatoes, frozen vegetables, bread and a lemon. Choose a personalized plan with overlapping ingredients, serving counts and flexible substitutions; compare its fee with the grocery savings you realistically expect.
Frequently asked questions
Does this plan treat PCOS?
No single diet has been shown to be best for PCOS outcomes. Mediterranean-style meals are one flexible option; personalize the plan to preferences, access and nutritional needs rather than expecting a cure.
