For the steak: Marinate the flank steak in the tiger sauce, lime juice, orange juice and garlic. Grill for 5 minutes per side. Rest for 10 minutes before slicing against the grain into thin slices.
For the halibut: Combine the lime juice, olive oil, garlic, jalapeno and some salt and pepper in a bowl. Add the halibut, turning to coat. Cover and marinate in the refrigerator. Grill for 3 to 6 minutes per side, depending on thickness -- the halibut will flake when done. Cut into small pieces.
For the tomatillo-avocado salsa: In a blender, combine the tomatillos, jalapenos, avocado, onion, lime juice, olive oil, cilantro, agave and 1 teaspoon each salt and pepper. Blend until completely smooth. Set aside.
For the jalapeno-lime slaw: Add the cabbage, cilantro and jalapenos to a large bowl. In a smaller bowl, stir together the mayonnaise, olive oil, lime juice, garlic powder and some salt and pepper. Toss the cabbage with dressing to taste.
To serve: Begin plating with a corn tortilla. Add a little less than 1/4 cup of slaw, top with a few pieces of halibut, a tablespoon or so of the salsa and a few slices of steak. Finish with crumbled feta, sliced radishes, if using, and a lime wedge.
