Step 1: Start by patting the salmon fillet dry and cut it into 1-inch cubes. In a medium-sized bowl, mix together the olive oil, lemon juice, honey, oregano, smoked paprika, Aleppo pepper, sumac (*optional), garlic, salt, and black pepper. Add the salmon cubes to the bowl, coat evenly, and put it in the refrigerator to marinade for 15 to 30 minutes.
Step 2: Cook grain of choice according to package directions. (*If meal prepping, cook grains ahead of time and keep them in an air-tight container in the refrigerator until it's time to serve!)
Step 3: Prep vegetables by chopping cucumber and tomatoes into a medium dice. Thinly slice red onion and avocado.
Step 4: Air Fry the Salmon. Preheat your air fryer to 400°F. Arrange the salmon cubes in the air fryer basket, making sure they’re not touching to allow for even cooking. Air fry for 6 to 7 minutes, shaking halfway through the cooking time. You’ll know the salmon is done when it flakes easily with a fork and has a nice golden color. Cook in batches, depending on the size of your air fryer.
Step 5: Prepare the Tzatziki Sauce. While the salmon is cooking, prepare the tzatziki sauce by combining Greek yogurt, grated cucumber, lemon juice, garlic, and dill in a small bowl. Season with salt and pepper to taste, then set aside.
Step 6: Assemble Mediterranean Salmon Bowls. Divide the grain among four bowls. Add cherry tomatoes, diced cucumber, sliced red onion, greens, avocado, and a sprinkle of feta cheese. Once the salmon is done, place 4 to 6 ounces on top of each bowl, add a large dollop of tzatziki sauce, then drizzle with lemon juice and extra virgin olive oil.
