Not haute cuisine, but these are quick, tasty, and nutritious, and kids (should) love them.
Drain a tin of red kidney beans, rinse well in a colander under the running tap and drain. Roughly mash them (a fork is better than a masher) and put into a heavy pot on the hob. Bung in a tin of ratatouille (Tesco sell it), and two handfuls of porridge oats. Add a glug of olive oil. Season to taste with salt, black pepper, chilli flakes, piri-piri, etc. Cover and turn heat to low. Cook for ten mins or so until the oats are cooked, stirring occasionally with a spatula.
Then take your wrap, bung some of the mix in, add some grated cheese, and roll it up, and cook in your microwave for however long your microwave takes for this sort of thing. Serve with soured cream. Makes enough for maybe four or five fajitas.
