Peel the carrots into long ribbons using a vegetable peeler. Steam or simmer them gently for 3–4 minutes until just tender but still holding their shape.
In a bowl, mix the olive oil, smoked paprika, tamari, nori, maple syrup, lemon juice, and black pepper.
Add the warm carrot ribbons to the marinade and toss gently to coat. Leave to marinate for at least 20 minutes (longer if you have time - overnight would be ideal)
Toast the bagel halves until golden.
Spread the bagels with the dip, then pile on the carrot “salmon”. Top with capers and fresh dill.
Finish with a squeeze of lemon and a little black pepper.
