Make the crumble. In a food processor, pulse all the ingredients until the mixture resembles fine crumbs. It should start to stick together a little bit. Transfer the crumble to a bowl and wipe out the processor.
For the dressing, into the processor, puree the ingredients until smooth. Taste for salt and pepper. Add a splash of lemon juice or water if it looks too thick.
Place the chopped greens in a large bowl and drizzle desired amount of dressing. Toss to coat. Serve with a sprinkle of the crumble on top.
