I don't have a food processor, but my hand held blender wand worked fine to process the ingredients. My only other substitution was lime juice from a squeeze bottle instead of lime zest and fresh squeezed juice.
The resulting flavor was amazing (I LOVE cilantro) and the whole process took maybe 20 minutes. I will definitely revisit this and make my own hummus moving forward. To make the lime flavor more pronounced, I might even follow the directions next time.
