You are probably going to fail some dishes at the beginning, it's okay. To know how hot it is, look at the flame underneath the pot, not all dials are reliable. It's my favourite way to cook meat, as it actually turns the heat down when you reduce the flame, unlike resistance electric that takes ages or induction that works as long as you haven't been cooking too long. Get yourself an electric kettle or you will need ages to get warm water for your pasta.
Get yourself some gas detector and get in the habit of opening the windows to ventilate. Take the normal recomanded precaution around open flames, turn the gas off at the arrival when you leave the house for longer than 36 hours.\

I like the very poor and lazy student greatness of peanut butter pasta. It takes barely longer than cooking the pasta themselves, the ingredients are almost all shelf stable and staples in my pantry... it's great for lazy cooking honestly. Okay, the recipe:

• cook pasta (however you like, I'm no pasta police)
• in a bowl, mix peanut butter with some soy sauce and vinegar (whichever brand/style/color you have at hand, we are being lazy here okay) the result can become a weird dense and sticky paste with a really deep soy sauce color and taste too strong to be good, do not panic, it's not finished yet.
• when the pasta is done, keep some of the pasta water and add it to the sauce, the sauce should now start to look good and taste much better.
• laziest option is to throw the pasta on top of the sauce and use only one bowl. If the sauce is too liquidy, you can reheat the hole thing a bit.

No need to add salt, it's already in the pasta water and soy sauce. Add whatever spicy thing you like, that works well. I wouldn't recommend adding cheese to it, I was never really successfull with it.
