Preheat oven to 200°C (400°F). Cut the potatoes into wedges, toss with olive oil, sweet paprika, salt, and pepper. Roast for 25-30 minutes until golden.
Season chicken fillets with salt and pepper. Set up flour, a mixture of mayonnaise and yogurt, and crushed cornflakes mixed with sweet paprika in three bowls. Dredge each chicken piece through the stations for a crunchy coating.
Cook the breaded chicken in a little oil until golden brown or bake alongside potatoes for about 15-20 minutes until fully cooked.
In a bowl, whisk together garlic, mayonnaise, yogurt, mustard, Parmesan cheese, salt, and pepper for the dressing.
Assemble by dividing romaine among bowls, topping with sliced chicken and roasted potatoes, then drizzle with dressing before serving.
