any tips? 24 178cm 112lbs

I’ve already started to lift weights 4x a week for 8 months which made me gain at least 8kg but I stopped now for almost 3 months since I underwent in a minor surgery.

I only eat anything that is available at home + 2 cups of protein shake (when I was working out) but I think I get acne from drinking whey protein that’s why I want to stop it also.

I want to go back in gaining weight but I’m not sure where to start again. Do you have any recommendations/tips that I could follow from workout routine and easy meal plans (maybe less the protein shake?) Any tips will be a huge help. Thanks!
