I confess I've become a fish snob since living in Alaska, so I wouldn't dream of feeding canned salmon to people (we give it to our dog)...but if it's all you have it will work. I actually used leftover from the patties I'd made earlier in the week.
2 pie crusts
6 eggs
1 1/2 c milk
1 1/2-2 c grated cheese (I did half mozzarella and half monterey jack, but swiss would also be good)
1 1/2 c shredded salmon (or about 1 can). You can also use leftover baked/grilled salmon if it's not heavily seasoned, but make sure it's thoroughly de-boned!
2-3 Tbs dill
salt & pepper
Preheat oven to 375. Bake (empty) pie crusts for 5 minutes.
Beat eggs, then add milk, cheese, salmon, and spices and mix well. Pour into slightly cooked crusts, then bake for 45 more minutes (it may need a little longer--test by inserting a knife in the middle of the quiche, when it comes out clean the quiche is done)
