How can one eat well despite having little money?

This is a question and be more answers. I am now over 30 and have the following tips:

either drink tap water (works in Germany) or cheap mineral water.

Buy noodles, rice, lentils and other basic foods on sale.

Don’t throw anything , noodles can still be , rice, and chips can be added to the pan.

Plan and your weekly shopping, because less shopping means less unnecessary spending.

Buy vegetables and at the wholesale market or on sale.

Meat is very expensive, if you really need it, you have to calculate everything again.

Prefer food that can be stored well.

Last but not least I recommend my cheapest lunch:

Noodles with tomato sauce (3 cans of chunky tomatoes, onions, herbs, salt)
