Here's a healthy alternative to pastry if you like making any kind of quiche.
125g split lentils (the orange ones)
1 onion chopped and saute'd in a little oil (or butter)
50g rolled oats
1tbsp tomato paste
1tsp dried herbs, or cumin, or garlic or other flavouring you like
Handful of grated cheese (any kind)
Salt/pepper to taste
Boil the lentils in twice their volume of water for about 10 mins and keep stirring so they break down into a thick paste. Add the oats, tomato paste and flavourings so it forms a sticky 'dough' you can press into a quiche/flan dish using your fingers or a spoon - it's too gooey to roll out. If it's too moist add a few more oats, if it's too dry add a little more water. You may have to fiddle with it.
That's your base. Put chopped veggies, fish, ham, whatever you fancy onto the base plus a couple of beaten eggs mixed with about half a cup of milk and sprinkle some grated cheese on top if required. Sorry my quantities are vague, I don't do precision!
Put in a hottish oven (180C) for about 20 mins or until it's lightly browned and obviously cooked. Allow to cool slightly and serve in slices with a fresh salad.
