1. Pre-heat oven to 200°C
2. Place the potatoes, beetroot, garlic, rosemary and 1 Tbsp of olive oil into an ovenproof casserole dish and roast for 30 mins until starting to brown.
3. Toss the asparagus into the casserole dish, broccolini, tomatoes and lemons to pot, and nestle the salmon amongst the vegetables. Return to the oven for a final 10-15 mins until the salmon is cooked.
