Carbs are bad.
But... You probably know. :P
Also: Salmon is not a lean meat: It's fatty. But animal fat is not really that bad.
Personally, I would avoid chicken and pork, though... Go for red meat like beef, lamb and goat, and eat eggs and fatty fish (like salmon and mackerel). Add dairy to the mix: Whole milk, yoghurt, cheeses and
quark/kwark/kvark.
Add leaf vegetables and fruit.
Also: Start working out. Protein-rich diets are great for gaining bulk, but if you want bulk, you'll have to work for it. That is: Unless you want to gain fat, in which case you probably want to eat lots and lots and lots of sugar/carbs, deep-fried in vegetable oil if possible, and not do anything ever at all.
