Recommend a protein supplement?

I've used premix Powerbar recovery drink powder for the last year, and it's definitely helped me control post exercise eating and seems to improve recovery. However, it's not exactly cheap - does anyone have a suggestion for a home made mix I can use that
a) will do the same job
b) cost less
c) will not taste like shit

Semi-skimmed milk with some skimmed milk powder. Need more protein... just add more powder.

I have a glass of almond milk with 2 tbsp of skimmed milk powder. I think that's around 15g of protein (and a little nutty goodness which I like the taste of).

I'm not keen on putting soya in me.
