I use mushrooms mainly to bulk up food, for example, I add them to cottage pie, lasagne, etc.. and they can turn 1lb of minced into 1.5lb. Also, I particularly like venison stew (which seems to require a huge quantity of mushrooms).
The problem that I have is that my daughter can't stand mushrooms, and studiously picks them ot of all her food. Is there an alternative for them for the two uses above?
