Chowhounds share some novel ideas for using Moroccan-style preserved lemons:
Add preserved lemons to ceviche and similar seafood dishes. Mince and add to aioli. Add a little to hummus. Or, stuff large olives with a strip of preserved lemon peel each–this is particularly fabulous as a Martini garnish.
Mince preserved lemons with parsley and oil-cured black olives and sprinkle on anything fried (potatoes, fish, shrimp, etc.). Combine chopped preserved lemons, chopped red onion, and mayonnaise, and use to top fish.
La Dolce Vita makes preserved lemon relish that’s good with roast chicken, grilled fish, and vegetables: Finely chop the equivalent of one whole preserved lemon; add about 1/3 cup total of finely chopped parsley, cilantro, dill, and green onion in whatever proportion you prefer. Add 1-2 Tbs. of good olive oil and 1/4 tsp. each of sweet paprika and toasted ground cumin. Let sit for about 15 minutes to give the flavors a chance to blend before using.
