Black beans and spinach in a folded wrap.

A small amount of beans can be easier to use when the meal has an edge you can fold over.

A warm filling

Try half a 400 g can of black beans, drained and rinsed; a handful of spinach; two small wheat wraps; one teaspoon of oil; and a little ground cumin.

Wash the spinach. Warm the oil in a pan, add the beans and cumin, and mash some of the beans. Add spinach and a splash of water, then cook until the leaves are soft and the filling is thoroughly hot, following the can’s directions.

Warm the wraps according to the packet. Spoon filling onto one half of each, leaving room at the edges. Fold over and return briefly to the warm pan to finish both sides. Cut in half to serve.

Begin with food you can safely use

The proposed batch uses canned beans. If you use leftovers, their storage history matters before you start cooking. Heating is not a way to undo unsafe storage.

Contains wheat. Adjust filling amounts after the first trial.

Development draft: not kitchen-tested. Quantities, texture and yield need checking.
