Coat a large saute pan with olive oil, toss in the diced onions and season with salt and crushed red pepper. Bring the pan to medium-high heat and cook the onions for 3 to 4 minutes. Add the garlic and cook for 2 to 4 more minutes. Turn the heat off and let cool.
In a large bowl, combine the lamb, the cooled onion mixture, the oregano, dill, mint, lemon zest and 1/2 to 3/4 cup water. Sprinkle with salt and combine well. Make a little "tester patty." Cook it and taste for seasoning.
Preheat the grill.
