Slice the bulb of garlic into thin wedges, then squash the tomatoes. Halve the lemon, then slice half finely.
Add a good drizzle of oil to a hot frying pan and fry the garlic until it softens and caramelises. Add the tomatoes and cook till they soften.
In another pan, heat oil on a medium-high heat. Season the salmon and cook, skin-side down, for 3 minutes. Turn, add the lemon slices to the pan, and cook for 2 minutes, or till the salmon is done to your liking.
Pick, finely chop and stir the mint and dill through the sauce, then tip over the salmon fillets and serve.
