Combine all the ingredients except the salmon in a medium glass bowl, stirring well to combine. Add the salmon fillets and toss with the marinade, making sure to coat all sides. Cover and place in refrigerator for 20-30 minutes.
Meanwhile, prepare the coriander/cilantro chutney. Combine coriander/cilantro, yogurt, mint (if using), chili, lime juice, sugar and salt in a blender. Blend until smooth, adding up to 1 T of water if necessary. (Be patient. It can take a bit to get it going and you may need to scrape the bowl and move things around a bit.) Taste and add additional salt or sugar as needed.
Preheat the oven to broil/grill and place oven rack about 6 inches from heating element. Spray a baking sheet with cooking spray (I cover it with foil first, but it is okay not to do that.)
Remove fish fillets from marinade, scraping off most of the marinade. Reserve marinade. Place salmon skin side up on the baking sheet. (If your salmon fillets are skinless, still put the side that had the skin up if you can tell which side it was.)
Broil for 3 minutes, keeping an eye on them as broilers can cook very differently. The skin should start to dry out and curl up a bit. Take the tray out of the oven and carefully remove the skin from the salmon (if applicable). It should peel off fairly easily. Using a fish spatula, turn the fillets over. You can use a brush to put a bit of the marinade on the side that is now on top.
Return the fish to the oven and broil for another 3-5 minutes or until cooked to your liking.
Serve immediately with chutney, lemon wedges and rice if desired.
