If you grow your own tomatoes and end up with some green ones in the autumn this is a great way to use them. Tomatillos are good here too, if you can find any. Otherwise, the cucumber
works really well and adds a hit of savoury to the pepper sauce.
As for the chillies, jalapeños are good for this and quite mild, but if you prefer to blow your socks off, try adding a bird’s-eye chilli. Look for corn tortillas rather than flour ones, as they are
more robust and won’t go soggy.
Preheat the oven to 220°C/Fan 200°C/Gas 7. For the sauce, place the peppers, chillies, garlic and spring onions on a large baking tray and drizzle them with oil. If using tomatillos or green
tomatoes, add them too. Roast for 20 minutes, then start checking for doneness. The vegetables will cook at different rates – you want them collapsing down a little and charring. The spring onions will take the shortest time. When all the vegetables are charred in places, remove from the oven.
Reduce the oven temperature to 200°C/Fan 180°C/Gas 6. Put the green peppers in a bowl and cover with a plate. Leave to steam until cool enough to handle, then remove the skins. Remove
the seeds from the chillies and squish the flesh out of the garlic.
Roughly chop the spring onions.
Put all the vegetables into a food processor with the remaining sauce ingredients and plenty of seasoning. Pulse until you have a coarse, fairly liquid sauce. Set aside.
To make the filling, heat the oil in a sauté pan and add the onions and red peppers. Cook gently over a medium heat until the onions are soft and starting to take on some colour. Add the remaining
filling ingredients along with 50ml of water and plenty of seasoning. Simmer until piping hot, then gently mash the beans so some of them break down. Remove from the heat.
To assemble, put a small ladleful of the green sauce in the base of an ovenproof dish. Lightly toast each tortilla on a dry frying pan, then add a tablespoon of the filling. Top with a teaspoon
of soured cream, then roll up and place in the dish. Repeat with all the tortillas, making sure
they don’t quite touch, then pour over the remaining green sauce. Sprinkle over the cheese,
then bake in the oven for about 30 minutes until the tortillas have browned round the edges
and the cheese is bubbling.
Serve with any remaining soured cream, lime wedges and some fresh coriander.
