I think there are protein sources that work well for lactose intolerant people (soy, pea, etc?). I'm not well versed in them but google it up, protein is key for staying in a positive nitrogen balance. If you're looking to gain nothing is as efficient as a scoop or two of your most important macro.
I struggle to eat enough calories as meals, so I make "fat shakes". Obviously you're gonna want to adapt this to your personal preferences, but: coconut milk and protein powder as your base, a little sweetener (stevia, sukrin), a litte salt, one avocado, a bit of peanut butter, and a banana if you're feeling wild.
I eat keto-ish... Olive oil, ghee, and coconut oils are all hugely calorie rich and can easily be snuck into food. Hellamns mayo is 700+ calories per 100g, so slathering it on some broccoli can quickly make up any caloric gap :)
