maybe here in the UK our chickpeas aren't as soft/mushy as they are in the US, but i found this recipe as it was written too dry to hold together as a burger, so i blitzed 1/3 of the mix in the food processor with an egg and some gram (chickpea) flour and then mixed it back with the rest of the mix to bind everything. only then did it make patties that wouldn't have fallen through the broiler rack. alternatively, you could substitute tahini instead of the egg (and leave out the sesame seeds) if you want to keep it vegan. i also needed to add a bit more salt & cumin than it called for, but that may be just personal preference. so, with these adjustments, i'll definitely be making these again!
