• Preheat the oven to 220°C/200°C fan/gas mark 7. Boil a large pot of salted water for the potatoes.
• Halve the potatoes widthways (quarter larger potatoes).
• When boiling, add the potatoes to the water, lower the heat to medium and cook until fork tender, 15-20 mins.
• Once cooked, drain in a colander and return to the pot, off the heat.
• Mix in a knob of butter and the oregano. Season to taste with salt and pepper. Set aside and cover to keep warm.

• Season the turkey with Central American spice, salt and pepper.

• Place a large pan over medium-high heat with a drizzle of oil.
• When hot, add the turkey and cook through, 5-8 mins each side. IMPORTANT: Turkey is cooked when no longer pink in the middle.
• When everything is almost ready, scatter the cheese over the cut side of the bun bases.
• Pop the buns into the oven and cook until the cheese has started to melt, 2-3 mins.

TIP: Cook in batches if your pan is getting crowded.

• Spread the aioli over the cut side of the bun lids.
• Top the bun bases with pan-fried turkey.
• Spoon over the Ballymaloe relish then sandwich closed with the bun lid. 
• Serve the herby baby potatoes alongside.
