I grew up with very simple foods, I started cooking when I was 12, loved to cook, then it my mid twenties I got very interested in other types of cuisine. I had an East Indian neighbor that taught me how to make curry, she was such a nice person.
I think if I were alone I would do much the same, except add meats to it, I'd probably cook enough for a month and freeze it.
Soups are wonderful, wintertime is when I make them, pea, bean, vegetable, chicken noodle an endless variety.
