A very small amount, unfortunately.
If you notice that the nut snack are generally around 11-12 nuts for women. That has about 80-100 calories, depending upon what book you read.
A can of chickepeas, at least mine had ~110 calories a 1/2 cup and the can contained 1 3/4 cups so that 385 for the beans alone, plus 1T oil ~ 120 calories.. so you are looking at 500 calories for the batch.
I would say 1/5th of the batch in keeping with the caloric value of the nuts.
