Ingredients for Grilled chicken Caesar sandwiches

2 garlic cloves, finely grated
30 ml fresh lemon juice
10 ml freshly ground black pepper, plus more
85 ml extra-virgin olive oil, plus more for grilling
90 g mayonnaise
60 g chopped cornichons (about 9)
kosher salt (to taste)

How to make Grilled chicken Caesar sandwiches
Whisk together the mustard, Worcestershire sauce, garlic, 30 ml of lemon juice, and 2 tsp of pepper in a medium bowl. Gradually add 80 ml of oil while whisking constantly until emulsified. Transfer half of the marinade to a small bowl, then whisk in the mayonnaise and cornichons; season the dressing with salt. Set aside.
Season the chicken thighs all over with salt and place them in the bowl with the remaining marinade; turn to coat. Leave at room temperature, turning occasionally, for at least 30 minutes, or cover and chill for up to 4 hours.
Prepare the grill for medium-high heat and lightly oil the grate. Grill the chicken, turning halfway through, until deeply browned and cooked through, 8–10 minutes. Transfer to a platter and let rest for 5 minutes.
Meanwhile, grill the buns, cut side down, until lightly toasted, about 30 seconds. Transfer to the platter with the chicken.
Toss the sliced fennel, fennel fronds, basil, and the remaining 2 tsp of oil and 10 ml of lemon juice in a medium bowl to combine; season with salt and pepper.
Spread the reserved dressing over the cut sides of each bun. Assemble the sandwiches with the buns, chicken, and fennel salad.
