Rinse and pat dry your lamb racks. Place each on a cutting board. Slice in between the ribs to yield individual pieces (see photo above). In a small bowl, whisk together the seasonings. Rub 3 tsp olive oil all over the lamb pieces and then season both sides with the spice mixture.
Heat 3 tbs olive oil in your large griddle pan. If you don't have a 2 burner pan you'd have to work in 2 batches. Once the pan is hot, add in the lamb pieces in an even layer. Cook for 2 minutes per side. If you want your lamb well done, cook for 3 minutes per side.
Green Goddess Sauce:
In a mini food processor, combine all the ingredients listed above and pulse until smooth, taste and adjust with salt, pepper or lemon juice if needed. Also add more milk/water if you want to thin out the consistency. Serve with lamb.
