...Trout. No but seriously, you hear alot of shit about magic bulking foods but this fish is great. Per 100grams of fish, it has 200cals, and 30 grams of protein. A average fillet is about 170 grams, and it really seems small. Just got 2 fillets, 350 grams together, thats 700cals and 90grams of protein.Not only does it taste allright, its also cheap, $3.95cad a fillet.
