Pre-heat over to 400 degrees. Spray coconut oil or cooking spray on your baking dish.
Keep your Mahi Mahi filets on a plate and salt and pepper both sides.
Cut a lemon into 4 slices. Place 2 lemon slices on the bottom of your baking dish. Set Mahi Mahi filets on top of the lemon slices.
Place in the oven and bake until fish is 145 degrees (between 8-15 minutes). Use a food thermometer to make sure your Mahi Mahi is cooked thoroughly. It should be 145 degrees at the center of each filet.
Heat a sauté pan medium low and add 3 tbs of butter. Let the butter melt while the fish is baking. Wash your cilantro and pull off the stem. Set to the side on a paper towel or small plate.
Once your fish is done baking, pour the melted butter over your fish while inside the baking dish.
Place 4 tortillas in a damp paper towel. Microwave for 45 seconds. You can also heat these up in your sauté pan until they’re warm if you prefer. I like to double up on tortillas so your tacos don’t fall apart (2 tortillas for each taco).
Lay your tortillas open on a plate. Add your Mahi Mahi filets. Depending on the size, you may need to cut them to the right portion for your tortilla.
Add 2 tbs of mango pineapple salsa, 2 tbs of cole slaw, and 1 tbs of guacamole to each taco.
Drizzle your crema sauce over each taco. This sauce has a little kick to it, so if you don’t like spice, you can skip it!
Add a couple pinches of cilantro to each taco.
