Starting to learn how to cook?

Every girl in my family started cooking and cleaning at the age of 13. While I, on the other hand, am 14 years old and I don't clean or cook. I figured, since I'm not a big fan of cleaning, I might as well start learning how to cook dinner every night. Do you have any tips for beginners, or recipes I can try? Maybe an online cookbook. And what tools do I usually need to make a ordinary healthy dinner? I need recipes that are healthy but very delicious. My family has major health problems because of the things they eat and they say that healthy food is gross and plain. It'd like to change their mind. Thanks for the help!
