See Hippy's post below, 2.2 is very high. He recommends 1.6 [though I stick to 2.0 when dieting, and it ain't fun...] but 0.4 gram per kg is really quite low.
Are you sure is it that low?
You can also try 1 gram per kg of your desired weight. If you know you carry 20 KG of pure lard, just deduce the lard. That leaves, say, 120 kg - 20 = 100 and 100 grams of protein in one meal is a bit of a A Sit.
But not impossible. eyes up chicken
Though you wrote also don't eat a lot of meat... yes, you can eat 100 grams with pulses/seitan/soy but I would not be able to digest that in one sitting I think.
A combination of a meat/fish and a pulse with some soy/seitan would do it though. But if you are already a picky eater, I think we need to identify first what you like to eat :)
I think I'm managing about 0.4 g/kg on average...
