Turn on broiler. Line a baking sheet with aluminum foil.
Place salmon skin side down on the baking sheet along with asparagus spears, drizzle both with olive oil and lemon juice then sprinkle with garlic powder and salt. Toss to coat.
Place baking sheet under the broiler to cook for 8-9 minutes, until salmon is cooked through and slightly browned on top.
Use a fork to pull apart the salmon then a knife to cut up the asparagus into bite size pieces. Place in a large bowl along with romaine hearts, avocado and caesar dressing. Toss and serve with some black pepper on top! Easy peasy lemon squeezy!
