First the pico de gallo - sorta - topping. Cut the ends off of the zucchini and thinly slice it. Chop the onion, the Roma tomato, the cilantro, the avocado and the jalapeño pepper. Put it all in bowl and add the cumin, salt, Cayenne pepper and the garlic powder. Squeeze the juice from the lime, drizzle a little extra virgin olive oil and toss it all together. Put it aside in the fridge while you tend to the fish.
Cut the catfish (or whatever fish you want to use) into short strips cutting across the filets.
Put a skillet on at medium high and eyeball about 2 tablespoons of olive oil. Put the fish into a bowl and add onion cut into thin strips (aka julienne), salt, pepper, chopped cilantro and the lime rinds left from juicing it into the pico. Toss it all together and put it in the skillet.
Gently stir or toss the fish as it cooks turning the individual pieces as necessary to get them cooked evenly. When the fish is firm and not spongy it's ready. It should take about 5 minutes.
Warm the tortillas wrapped in a towel in the microwave for 30 seconds. Then put the fish in the tortillas and top with the faux pico de gallo. This is a very good quick easy fish tacos recipe. Enjoy!
