Vegan meat from the supermarket is delicious but not a sustainable option for a weekly diet: too much salt and preservatives.

Recipes such as black bean & beetroot burgers are superb. I'm on the lookout to more classic recipes, maybe using soy protein or even anything more complicated as long as it doesn't need an industrial kitchen.

Also lentils are filling and have a lot of protein. Boiled lentils with salt and other seasoning taste fine, are easy to make and as unprocessed as it gets.
