you learn to cook pretty quickly with whatever the heck you can
get your hands on if you have a budget...
i lived on a strict budget because we put away the excess for beer

go walk around, learn the neighbourhood, learn to be streetsmart..
figure out how and where to get the best value-for-money things...
for example, we go for fresh produce at the markets about 1/2 hour
before closing and the stallholders will flog stuff to you at
around 20% of the usual price early in the morning..
a couple of kg of mince beef goes a long way.. you can cook tacos,
make beef patties, make spaghetti sauce, meatballs..
things like that, you learn because of necessity
