The ingredients in the salad dressing seem surprising, but trust us: toasted cumin, fish sauce, cilantro and Merken is a delightful combination.
First, make the dressing. Place lime juice, scallions, coriander, fish sauce and merken in a bowl.
Toast cumin in a small pan until fragrant. Stir into the dressing then incorporate the oil.
Roast pepper in oven on broil until the skin is blackened. Place in a bowl and cover with a plate. Let stand 10 minutes and skin the pepper.
Dice the pepper. Add remaining ingredients to the dressing. Stir well and let rest 20 minutes before serving.
