food@jeder i mean cooking noodles is basically 1) boil water with a bit of salt 2) add noodles 3) wait for noodles to become right consistency, taste one or two, often packages have recommended time on them 4) remove water
potatoes are pretty much the same. rice is also pretty much the same if you use parboiled rice.
pizza you can buy in "pizza kits" with pre-made dough and sauce where you just put the toppings on yourself and then put it in the oven.
