What are some healthy foods and snacks that will help me gain weight? Please help!!?

I’m trying to gain weight because I really want to have a beautiful, natural thick body but in order to get an hourglass/pear body I need to gain a little weight, but HEALTHY weight. I’ve already been eating foods like dried fruit (apricots and prunes), berries, milk, cheese, rice, fish, chicken and turkey. I also ONLY drink water, No juice or sugary drinks. I would say I have seen small results I’m putting on a few pounds especially around hips. I do butt workouts every night and take like a half hour walk every evening. I think I’m doing good, please tell me If you recommend anymore foods, drinks and exercises that will help me gain weight and get a hourglass/pear body shape. I’m going ALL healthy and natural stuff. I am against butt injections and needles.

Just for realism I drew a demonstration on how I want my body look like. Please forgive me if it looks horrible! 😂 I tried to make it look as realistic as possible!
