Toss the cauliflower florets with 1 tbsp olive oil and Salt and pepper to taste
Spread the cauliflower on a baking sheet and roast for 20-25 minutes, stirring midway, until golden brown and tender.
Heat a skillet over medium-high heat. Cook the steak for 4-5 minutes on each side, or until it reaches your desired level of doneness (135°F for medium-rare, 145°F for medium).
Let the steak rest for a few minutes, then slice thinly against the grain.
In a large bowl, combine the mixed spring greens, snow peas, sunflower seeds, red bell pepper and the roasted cauliflower.
Add the sliced strip steak on top. Drizzle with the soy lime vinaigrette and toss gently to combine. Garnish with sliced green onions.
