Heat oven to 200C/180C fan/gas 6. Grease
a baking dish and fill with the torn bread.
Heat the butter in a large pan until it starts
to foam. Add the leeks and garlic, and cook
over a medium heat for 5 mins, stirring as
you go. Spoon softened leek mixture over
the bread and top with cherry tomatoes.
Beat together the eggs, milk and
cheddar. Season, then pour over
the bread and bake for 15-20 mins
until golden and puffy. Serve with
ketchup, if you like.
