Thinly slice the radishes and red onion using a mandoline. Roughly chop the chervil.
Peel the grapefruit to remove the pith, then segment it by cutting between the membranes to extract the flesh.
Remove the seeds from the pomegranate.
Slice the block of halloumi in half lengthwise, then cut it into cubes. For a festive touch, use cookie cutters to create shapes like stars.
Heat a skillet over medium-high heat with a drizzle of oil. Grill the halloumi for 4-5 minutes on each side. In the last minute, drizzle a tablespoon of honey and squeeze the juice of half a lemon over the halloumi, stirring to coat evenly. Be careful not to overcook, as halloumi can burn quickly.
Combine all the dressing ingredients in a bowl and whisk together.
Assemble the salad by layering the mâche, radishes, red onion, grapefruit, pomegranate, and chervil. Top with the grilled halloumi and drizzle with the dressing before serving.
This salad is sure to impress with its balance of flavors and vibrant presentation!
