My goto would be curry or stir fries - if your making a curry add spinach as that is high protein, add a side of daal (lentil) and that will really boost the protein.
Personally I wouldn't rely on quorn to be your protein source, its expensive, processed and you could get a bit bored of it (it also contains milk). A great source of protein is chick peas - if your not a fan of eating beans, blend them up with some garlic and use this instead of mayo in sandwhiches etc, if you want to up the protein further blend them with some yogurt. Most beans and peas are high in protein and easy to add to a lot of dishes (blended peas or beans in a paste and served on crusty bread - add a bit of cheese).
Peanut butter is another great source of protein (nuts in general are), add a handful of nuts (ooh err missus) to your breakfast cereal. I love sesame seeds, throw a handful of them in a salad.
Tofu is ok - I don't use it as bf hates the stuff.
