Chickpea Fajitas

1. Heat oven to 200C/180C fan/gas 6 and line a baking tray with foil. Drain the chickpeas, pat dry and tip onto the prepared baking tray. Add the oil and paprika, toss to coat, then roast for 20-25 mins until browned and crisp, shaking halfway through cooking.
   20–25 minutes
2. Meanwhile, put the tomatoes and onion in a small bowl with the vinegar and set aside to pickle. Put the avocado in another bowl and mash with a fork, leaving some larger chunks. Stir in the lime juice and season well. Mix the soured cream with the harissa and set aside until ready to serve.
3. Heat a griddle pan until nearly smoking. Add the tortillas , one at a time, charring each side until hot with griddle lines.
4. Put everything on the table and build the fajitas : spread a little of the harissa cream over the tortilla, top with roasted chickpeas, guacamole, pickled salsa and coriander, if you like. Serve with the lime wedges for squeezing over.

Cooking notes

Most vegetable dishes scale linearly, but be mindful of pan crowding — vegetables that should brown will steam instead if packed too tightly.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
