How to get enough protein and calories (without dairy)

[Hemera]

Hi

I'm currently pescterian (fish but no meat) and would like to become fully vegetarian but what worries me is eating enough. I have a poor appetite at the best of times and can't eat too much in one sitting. I'm not able to eat processed food, I'm gluten intolerant and I'm allergic to dairy so that is a no no. I can and do eat eggs but don't want to over-rely on them.

Any ideas for upping both calorie and protein intake? My diet is pretty good just a bit lacking. I eat mainly gluten free grains but with some spelt pasta which I seem to be okay with, beans, lentils, chickpeas, eggs, some nuts and seeds (mostly as butter, as I'm not keen). I use violife cheese sparingly to top some dishes. And at the moment I'm eating a variety of fish to top my intake.
