Cilantro Lime Tilapia Tacos

From Skinnytaste.com
Dave doesn't like chunky tomatoes so I used skinnytaste.com's creamy tomatillo cilantro dressing instead of a bunch of the ingredients in this recipe.

1 lb tilapia fillets, rinsed and pat dried
1 tsp olive oil
1 small onion, chopped
1/2c creamy tomatillo cilantro dressing
8 5-inch white corn tortillas
1  medium haas avocado, sliced
lime wedges and cilantro for garnish

Heat olive oil in a skillet. Sauté onion until translucent, then add garlic. Mix well.

Place tilapia on the skillet and cook until the flesh starts to flake. Add dressing. Sauté over medium-high heat for about 5 minutes, breaking up the fish with the spoon to get everything mixed well.
Meanwhile, heat tortillas on a skillet a few minutes on each side to warm (no oil needed). Serve a little over 1/4 cup of fish on each warmed tortillas with a slice or 2 of avocado and some extra dressing drizzled on top.
