Preheat the oven to 400F/200C and line a baking sheet with parchment paper. Mince 2 garlic cloves and add them to a bowl. Add 1 Tbsp of lemon juice, 2 tbsp of olive oil, ½ tsp black pepper, and ½ tsp salt. Mix and set aside.
Add the sliced almonds to the prepared baking sheet and drizzle with 1 tbsp of garlic lemon mixture prepared earlier. Toss and transfer to the oven.
Bake for 5-7 minutes until golden and crispy, then set aside. Add the shrimp to the bowl with the remaining lemon garlic mixture, mix to combine, and let marinade for 5 minutes. Place a nonstick pan over medium-high heat.
Fry the shrimp for 1-2 minutes on each side. Don’t overcook the shrimp, or they will get rubbery. Set aside.
To make the Caesar dressing, combine the yogurt, mayonnaise, 1 garlic clove, 1 Tbsp lemon juice, grated parmesan, anchovy fillet, mustard, ½ tsp salt, and ½ tsp black pepper in a food processor. Blend until well combined. Taste and adjust seasoning to your liking, then set aside.
To assemble, tear the lettuce into bite-sized pieces and add it to a serving plate. Add ½ the dressing and toss to coat. Slice the avocado and add it to the lettuce.
Top with shrimp, shaved parmesan, and crispy almond slices. Drizzle the remaining dressing on top. Serve immediately!
