Cut Halibut into 1x1 cm cubes. Add to a bowl and pour the juice of 1 lime.
Let it rest in refrigerator for 10 minutes. Meanwhile, you cut the vegetables.
Sprinkle salt on the fish cubes and mix in the green chili.
Arrange on a serving platter, adding the red onion, passion fruit (use a spoon to carve out the inside) and top it all with a swig of olive oil. You may want to finish with some fresh herbs.
Have fun and enjoy!
