Hi, welcome to the boards. You are going to need to count your cals to make sure you are getting enough food to grow. Eat good foods, turkey, fish, beef, chicken, tuna, whole grain carbs pasta, brown rice, good fats, natural pb, eggs, olive oil etc. Lots of veggies too, fruits if you'd like. Make sure you are getting at least 1.5x lb of bodyweight for protein so around 220g protein, which comes out to just under 900 cals. Rest carbs / fats, I tend to just eat very high protein / carb and try not to go too hard on the fats. ~50-60g a day for me. If you are not gaining at least 0.5 lbs a week / 1 lb every 2 weeks I would up the cals a bit until you are. The slower you bulk the less fat you will put on, hope this helped.
