Very different weight question?

Well I know we've all read weight loss articles. Given and received some advice on how to lose weight. You've tried a diet or two at some point because we want to meet the worlds definition of what's beautiful, skinny.
So I'm one of those skinny girls, weighing 52kg, I'm a petite. I'm happy with my bodies weight and height BUT I've been the same size for the past 5years. So I'd really love to gain weight just a little bit. Thing is I've never had of a HOW TO GAIN WEIGHT DIET... or am I being ridiculous. Mind you I eat very large portions n my lunch is always a lot of junk
