Annie's potato & tomato bake

Heat the oven to 190C/fan 170/gas 5. Thinly slice the potatoes either by hand or in the food processor (no need to peel them). Put in a pan with water to cover, bring to the boil, simmer for 3 mins, then drain well. Slice the tomatoes.

Brush oil over the base and sides of a 1.5 litre ovenproof dish. Layer up half the potatoes, seasoning and drizzling with oil as you go, then cover with half the sliced tomatoes. Repeat the layers, finishing with tomatoes.

Bake for 45-55 mins, until the top is lightly browned. Serve warm or at room temperature. Can be reheated.
