Wash your filet of fish and put on foil or parchment paper.
Put a thin stream line of olive oil around fish to avoid sticking. Put a zigzag of sweet and spicy mustard on the fish. Add fresh dill, pepper and a bit of garlic powder.
Cut slices of onions and place on top of fish and grill for about 7-15 minutes pending on thickness.
(You can add 2 tsp. jalapeño pepper or a dash of Tabasco if you like a bite. You can add fresh Clementine if in season)
Serve 6 ounces of fish with a scoop of salsa with a steamed fresh vegetable like green beans or carrots.
Garnish with cilantro, mint or both.
Enjoy. This is delicious!
As always, be conservative with the salt; it will retain water and slow down your metabolism.
