$10 for a daily subscription to Ensure 2.0? You can eat eggs, slow cooker cuts of meat, seasonal fruit vegetables, rice, beans, flour, salt, yeast.. etc for $10 a day easy. As long as one is not too allergic to washing a few dishes, that is.
Soylent is too expensive. It's a very attractive solution for me but the price point is higher than real food. Soylent needs to be like $1 a meal, with super duper high protein, if it wants to compete with home cooking.
I can make a fine French dining quality 4-6 egg omelette, with a reheated beans and vegetables on the side, for like $2 a plate. A big plate, too.
