Aside from the fact that hunger is not caused by lack of food but by a capitalist distribution of means of subsistence, that also sounds profoundly unsafe. So you want to grind raw meat, raw eggs, with berries, leeks, idk what else, and hope for the best? Some of the food might have been on the verge of expiration. If some of the food was bad now all of it is bad because you mixed it all up. Different ingredients need different cooking methods, temperatures, times, etc. Some of your paste will be cooked to inedibility whilst some of it won’t be at a food-safe temperature yet. Even if it didn’t cost anything to implement this, no one had any dietary requirements, etc, this food would just be unsafe to eat.
