My mare is really not fussy. If its in your hand/pocket, she wants it!
She has a sausage roll and a lick of port off my fingers when we go hunting, she loves watermelon, wotsits, Haribo (OH was in BIG trouble when I found out he had given her half a bag of Starmix "because she likes them", and even more trouble when I found out it happened on more than one occasion!), she picks up pop bottles for a swig - if you leave a fanta bottle in front of her its all gone in seconds, leaving her chops in an orangey sticky mess! She also has some bread with ketchup off my bacon sandwich when we go competing. I draw the line at the bacon, a mini sausage roll every now and then at a meet is bad enough!
I have one that LOVES absolutely everything! and i mean that everything! Any type of crisps/sweets/cake/sandwiches you name it he loves it, i think he thinks if i'm eating it he needs it.
Our old boy Jimmy used to like the odd bottle of 7up. He once pinched my bacon sarnie at a show.
Hubbys mare Bramble likes mars bars, and both our old pony and my youngster like the odd chip.
My TB likes anything with sugar in it. His favourite is liquorice and his weirdest favourite treat is flavoured milk. My pony will eat anything the TB eats even if he doesn't like it because he doesn't want to miss out.
Bob will taste almost anything, and eat most of it. He's tried to have ham and cheese, and egg salad with scallion, I can't eat anything near him without being asked for some. (read nudged until I get fed up and give in/give out to him, depending on what I have). He like sweet chilli flavour walkers, nature valley bars (but they're oats, so they must be horse food). He once robbed half a breakfast roll, back when we were in pony club!
If someone (human or horse - especially food from other horses' mouths) else is eating it, he likes it!
Anything!! Tea, coffee, biscuits, crisps, cakes and Krispy Kreme donuts. I must add he doesn't get these things often and only a small piece he does eat hay mostly
my mare LOVES crisps, any flavour, any kind she will eat! even chili heatwave doritos! but she goes mad for walkers cheese and onion she spits pears and chocolate out with a look of horror on her face though!
