Moreish

moreish, morish [?m??r??]
adj
Informal (of food) causing a desire for more.

Just some of the mountain of mallow 'flumps' that were bought on Sunday. The barrel is certainly going down quickly - they are so moreish!

Other things that are 'more-ish' in my opinion:
Walkers Sweet Chilli crisps
Jelly Belly Beans
Bon Bons
Pringles
Maltesers
Custard Creams
Milk gums
Twiglets
Cheese thins

Why can't tomatoes and cucumber be moreish? Think how much healthier we would be..
