Preheat oven to 425°; chop cauliflower into 1-inch pieces, spread on a sheet pan, toss with 1 tbsp oil + season with salt/pep; roast 10 min, flip + roast 5-10 min more til tender

Meanwhile, pat fish dry + season with salt/pep/fave spices; heat 1 tbsp oil in skillet over med-high (get that pan hot, otherwise the fish will stick) + sear 3 min, flip + sear another 1-2 min (for well done cook 3 min on second side)

Pour cheese sauce into a small pot + heat over med-low, 2-3 min; mix thoroughly

Add salad kit to a large bowl, drizzle with dressing + toss to combine; divide everything between plates; drizzle cauliflower with cheese sauce—nice job!
