Hey all,
years ago a friend got me onto TVP (textured vegetable protein), it was our staple bush food. Directions were simple, ad boiling water, stand, add a stock cube, add spices, eat with pasta, rice, wraps...
Haven't seen it for years but I found Planet Organic Organic vegetarian mince. It is pretty much the same stuff - hooray. Half a cup is a huge single person serve, it absorbs twice it's volume in water! It takes on the flavour of stock cubes well. Its dry weight is light (22gms per serve). 50% protein but is not nutritionally dense food, so if you are doing an extended trip and don't have a spare tire or some love handles you might need to keep the meal portions LARGE.
