You can always make a quick bean curry and add the Chickpeas - I'm not a fan of canned foods but when it comes to legumes and pulses, it's often a lifesaver so now always have a selection of those on hand.
With these meringues, some say that they melt quite quickly but mine has been fine and we live in a very humid climate so it would be a good idea to put everything together at the last minute with a pavlova.
I hope we're going to see your Aquafaba creations here:) It's really magical stuff!
