Mix everything together and fry in a buttered frying pan. Makes one serving. 4.6 g carb, 447 calories, 39 g fat, 19 g protein. (But probably different for you, with other brands of cheese, soy powder, and wheat gluten, so do your own math).
You can try substituting cream cheese for the mascarpone (I don't like cream cheese, myself). Maybe even cottage cheese for the ricotta (in which case, don't add any salt...).
