In a bowl, combine the medium shrimp with Cajun spice, pressed garlic, and a pinch of salt. Toss to ensure the shrimp is well coated with the spices.
In a medium skillet, melt the unsalted butter over medium heat. Add the seasoned shrimp and cook for about 2-3 minutes on each side until they turn pink and opaque. Remove from heat and set aside to cool slightly.
While the shrimp is cooking, chop the romaine lettuce into bite-sized pieces and place it in a large mixing bowl. Slice the Roma tomatoes, red onion, and cucumber, then add them to the bowl with the lettuce.
Carefully slice the avocados and add them to the salad bowl along with the corn kernels. The sweetness of the corn pairs beautifully with the creamy avocado.
In a small bowl, whisk together the lemon juice, extra virgin olive oil, sea salt, and black pepper. Adjust the seasoning to your taste.
Pour the dressing over the salad ingredients and gently toss everything together. Finally, add the cooked shrimp and chopped cilantro (or parsley) on top, giving it another gentle toss.
Transfer the Shrimp Cobb Salad to a serving platter or bowl. Serve immediately and enjoy a burst of flavors in every bite.
