a) If you don't have a microwave, heat your oven to 220°C/200°C fan/gas mark 7 for the tortillas.

b) Drain and rinse the black beans in a sieve. Pop a third of the beans into a bowl and mash with the back of a fork.

c) Peel and grate the garlic (or use a garlic press). Zest and halve the lime (see ingredients for amount).

d) Drain the halloumi, then cut it into 2cm chunks. Place them into a small bowl of cold water and leave to soak.

a) Heat a drizzle of oil in a medium saucepan on medium-high heat.

b) Once hot, add the garlic and tomato puree. Cook, stirring, for 1 min.

c) Pour in the water for the sauce (see pantry for amount) and add the whole and crushed beans. Mix together and cook for 3-4 mins.

a) Add half the chipotle paste to the beans (add less if you'd prefer things milder).

b) Mix well and season to taste with salt and pepper.

c) Allow to simmer until thickened, 2-3 mins.

d) Meanwhile, remove the halloumi cubes from the cold water, pop them onto a plate lined with kitchen paper and pat them dry.

a) Heat a drizzle of oil in a large frying pan on medium-high heat.

b) Once hot, add the halloumi and fry until golden, turning frequently, 4-5 mins.

c) Meanwhile, mix the remaining chipotle paste with half the mayo in a small bowl.

d) In another bowl, mix the remaining mayo with the lime zest.

a) Pile the tortillas (3 per person) onto a plate. Heat them through in the microwave, 850W: 50 secs / 750W: 1 min, until warm and soft.

b) If you're using the oven, lay the tortillas onto a baking tray and place on the middle shelf to warm through, 1-2 mins.

c) Trim the baby gem, halve lengthways, then thinly slice widthways.

a) Spread the chipotle mayo over each tortilla.

b) Top with a handful of lettuce and a squeeze of lime juice.

c) Spoon over some chipotle bean mix, then top with the fried halloumi cubes. Drizzle over the zesty mayo to finish - as much as you'd like.

d) Serve the tacos with any remaining lime cut into wedges for squeezing over. TIP: Tacos are best enjoyed eaten by hand - get stuck in!

Enjoy!
