To make the salmon salad: Whisk together all of the marinade/dressing ingredients (olive oil, lemon juice, dill, oregano, red wine vinegar, salt, and pepper) in a large mason jar. Pour out half of the marinade into a large, shallow dish. Refrigerate the remaining marinade to use as the dressing later.
2. Coat the salmon fillet with the marinade. Heat 1 tablespoon of oil in a skillet over medium heat. Sear salmon on both sides until crispy and cooked to your liking.
3. While salmon is cooking, prepare all of the salad ingredients (romaine lettuce, tomato, avocado, cucumber, and red onion) and mix or arrange in a large salad bowl.
4. Slice salmon and arrange over the salad. Drizzle the salmon salad with the remaining dressing that you kept aside at step 1. Garnish with lemon wedges and serve immediately, or refrigerate. Enjoy!
