I have a recipe card from tesco which makes the case from thick bread moulded into small saucer shape and filled with mix of tuna, sweetcorn, spring onion and mayonnaise. cant elaborate more as I am at work and the recipe card at home.
Just to add you put bread circles in muffin tray and bake for ten mins at gas 200. It says with the help of an adult place tray ib oven!
Now i see this recipe says suitable for 6-7 year olds....
Peppadews filled with cheese are already on the menu :-)
I am toying with the idea of something sausagey. I prefer them hot or at least warm I'll just have to tie a know in my hanky to remind myself they're in the oven.
