In my experience fussy eaters aren't created they are born that way and can be coaxed (quite successfully) into being adventurous eaters.
Neither of my two were great at the start either. Heck DS chose to only eat frozen peas for a fortnight a while back, and my DD was a yoghurt lover too. Neither of them ate well until well over 1. I have the only two children i know that will eat a laksa or butter chicken or garlic prawns. There will always be wasted food while they're learning. They will only eat to satisfy themselves - gluttony is a learned behaviour, so often their definition of enough is markedly different to yours. Food isn't their main source of nutrition until after 1 so as long as she's still BFing /drinking her bottles don't worry about her levels. Food is a discovery as much as filling a need. The texture/smell/tactility/taste is all new. Try giving her a piece of meat to suck on (a decent sized piece if you're worried about choking).
SOme things I have discovered in my years of trying to get children to eat
don't make it a battle - if they are hungry they'll eat and won't starve, but the second they smell a fight- they'll be itching to take the side opposite to yours
offer a variety all the time, but also offer what they like as well. I know it's a bit hard with yoghurt but I offer what my DD calls a 'picnic plate' when they're being a bit fussy with chopped up vegies, fruit, crackers, sandwiches cut out with a biscuit cutter, savoury muffins etc, but only a tiny bit of everything so it doesn't look too hard to eat.
roll model good eating habits
make it fun, let her eat outside/on a towel on the floor etc and have her help you make it. Pop her up on the bench and pick out what she'd like
often eating off your plate is far more exciting than their own
