2: Prepare the marinade by mixing 6 tablespoons olive oil, 1 lime, herbs of your choice (bay, rosemary and thyme here), salt and pepper.
3: Tip the fish into the marinade, mix well, cover with plastic film and leave to marinate for at least one hour.
4: Prepare and cut the mushrooms into large pieces.
5: If not already in slices, slice the bacon thinly and cook in the oven at 360°F (180°C) on a wire rack until lightly browned.
6: Cut the slices across into squares.
7: Make up the slewers, alternating fish with mushrooms and bacon. If you are not going to cook them immediately, put them on a plate and sprinkle what is left of the marinade over them.
8: Grill or, preferably, barbecue, turning until cooked on all sides (They can also be cooked on a griddle or in a frying pan if necessary).
Remarks
You can vary the ingredients as you wish, for example by using prawns, crayfish or scallops instead of the fish.
