Learning to cook

My husband has done the cooking all these years and I've been happy to let him do it.  Now that he is a trucker and will be gone much of the time, I have to learn to feed myself.  My children are grown so it's just me I have to worry about.  My first attempt was boneless skinless chicken breasts which, when thawed, turned out to be skin on chicken thighs with bones :(  I attempted to cook them the way I was directed for the chicken breasts and well, they were edible but just barely.  I'm sure I'll get better at it.
