Tuna Cheddar Savoury Tart

I got this recipe from my sister who got it from a friend. I don't know where it originated from but it is very good.
A friend of mine that I worked with asked me for this recipe this morning. I have not made it in a while and I maybe it is time for me to make it again.

Crust

1 packet Cheddars biscuits (crushed)
60 g butter (melted)
Put two T crumbs aside

Mix the crumbs and the butter and press into a pie plate.
Set aside.

Filling

2 tins tuna fish (drained and flaked)
1 medium onion (chopped)
1 greenpepper (chopped)
1 c Carnation milk
1 egg
1 t prepared mustard
Salt and pepper to taste

Fry onion and greenpepper until soft.
Add the rest of the ingredients for the filling and pour into the crust.
Sprinkle the 2 T crumbs over the tart and bake at 170 degrees C for 30 minutes.

This will go well with a salad as a light meal or on its own as a snack
