feta as in feta cheese
It depends on the recipe, but probably not. Goat cheese is more delicate flavored and not as salty. It has a different texture, too. Feta is chunky, whereas goat cheese is more crumbly. If all you're doing is crumbling it into a salad, it's probably OK (but remember that feta is much sharper tasting). But if cooking is involved, I don't think it would work well.
There are many pizza recipes that use feta cheese. For example one could make a Greek pizza with spinach and feta cheese. As a topping feta cheese goes very well with olives.
Same way. Except when you stir it the part where you add american cheese or swiis. You put cottage cheese instead.
Feta is one such cheese, Manouri another.
