Dry the cherries on paper towels. Place the garlic and red onion in a food processor and pulse to chop. Add the chipotle in adobo, cilantro leaves and lime juice and pulse to combine. Add the cherries and pulse just until they are roughly chopped. Place in a small serving dish and reserve.
Combine the ground cumin with the salt and pepper in a small bowl. Brush the tilapia filets on both sides with the olive oil. Sprinkle the cumin seasoning mixture on both sides of each fillet.
Heat a skillet or grill pan over medium-high heat until hot. Add the tilapia and let cook without moving for 2 minutes. Flip and cook on the other side for 2 more minutes or until the fish is cooked through and starts to flake. When done, flake into a serving bowl and cover to keep warm.
Heat the tortillas and serve. Let everyone make their own by adding a small handful of cabbage to each tortilla, topping with some fish then salsa. Add a squeeze of fresh lime juice and more cilantro if desired. Fold the tortilla over and enjoy
