Snap the woody ends off the asparagus.

Add pasta to a pot of boiling water, lower to simmer and cook as per the pack instructions. Add the peas for the last 5 mins if frozen, 2 mins if fresh.

While the pasta is cooking, add the asparagus to a pan on a medium high heat with olive oil for about 5 minutes, till tender but still crisp and nicely charred. Add the garlic for the last minute. Remove from the pan, add more olive oil and the salmon. Fry for 2-3 minutes, turn over and fry for 1-2 minutes, or until cooked through. Set aside.

Drain the pasta and peas. Chop the asparagus into 1inch pieces, add to the pasta with the olive oil, lemon juice, tarragon, salt and pepper and flake the salmon over the top.
