Preheat oven to 450°F.
On a large baking sheet, toss the brussel sprouts, sweet potatoes, and halved lemon with olive oil, salt, and pepper. Roast for 20–25 minutes, mixing once or twice, until golden and tender.
While the vegetables roast, bring a pot of salted water to a boil. Cook the orzo until al dente, then drain and toss with a little olive oil to keep it from sticking. Set aside.
Make the Vinaigrette: Once the veggies are done and the lemon is golden and softened, squeeze the roasted lemon into a blender. Add the dill, garlic, chives, Dijon mustard, apple cider vinegar, agave, olive oil, and a pinch of sea salt. Blend until smooth.
Season the salmon filets to your liking, then pan-sear with a drizzle of olive oil. Swap in a different protein like chicken, steak, or shrimp here if you'd like!
Assemble the Salad: In a large bowl, combine the roasted vegetables, red cabbage, chickpeas, broccoli-carrot slaw, green onions, orzo, and your greens of choice. Drizzle with the vinaigrette and toss gently to coat.
Top with your pan-seared salmon and enjoy. If you’re prepping ahead, store the vinaigrette separately to keep everything fresh.
