Roughly chop the broccoli rabe and measure 1 cup of the cooked vegetable. In a food processor, pulse the toasted almonds with the garlic until finely chopped. Add the cup of broccoli rabe, the olives, and parmesan. With the food processor running, slowly pour in the 1/4 cup olive oil (4 tablespoons). Scrape down the sides of the bowl with a rubber spatula. Continue processing for 30 seconds to 1 minute. The contents should look like a bright green paste. Taste and add a pinch of salt if necessary. If the broccoli rabe was blanched in sufficiently salty water, the mixture should not need any more salt.
