What is the best way to eat to save money ?

I'd suggest only buying what you know you are going to eat. Male smaller portions. So you don't have waste. And eat healthy fruits and veggies that are on sale. Buy dry pasta, rice and beans and cabbage and take the time to cook and meal prep properly. Eat or freeze the leftovers. Farmer's markets are great if the prices are low-espeically for expensive things like honey, herbs and dried peppers and spices.
