My mom wont let me cook?

She doesnt even let me boil water! Im 12 (Turning 13 in July) and when I get older Ive been pretty set for bein a chef..But if I dont get any practice or anything how am I supposed to learn??We dont learn at school because its Catholic school. She makes me so mad because the only food we have requires to be cooked (Like pasta,ramen,macncheese ECT) Im allowed to use the microwave (thats it) and we dont even have a god damn toaster! Ughhh and im really hungry now and she wont be home for a few hours so idk what to do..No cereal either..I want real food not like the slop I usualy make in the microwave
