Never been there, never done that, but it seems one of the things you could be doing is to put up the most interesting ideas you have on sites, just to gain the operational experience and to see what it takes to transfer an idea, any idea, into served bits.

Sidenote: as for "ramen profitable," for anyone in the situation where they're eating ramen or similar to survive, don't. Ramen's expensive and not great for you.

Buy dry black beans and vegetables. Soak the beans over night (rinse a few times during the process), then boil the beans the next day as you cut up carrots, peppers and onions. Saute the peppers, onions, garlic and similar, wash and cut up the carrots, saute with the rest just to have some place to put them. Other vegetables too if you like.

Pre-heat the oven to 300 F.

Rinse the beans once more, dump everything in a big oven pot (which you bought with the money you saved from not eating ramen and going under-nourished). Add about two cups of water, half cup of wine that can be drunk, or quarter cup of apple cider vinegar if you don't have wine. Or neither. Whatever spices you have.

Cook in oven about 3 to 4 hours. This will feed you for days. 16 oz black beans costs $1 here; the above bean stew costs in total $5 US or less. And there's actual nutrition in there, as opposed to ramen.
