Give her a spoon and let her try to do it herself and while she is trying to scoop the food up see if you can sneak a spoonful into her mouth

I had to do this with my daughter, quite often I was able to feed her half and she managed to get the other half herself. Or load a spoon for her but let her put it in her mouth herself. It's far better to let her get on with it and learn as it makes it much easier at mealtimes once they can feed themselves!
Quick lunches; at that age my daughter loved slices of ham and chicken, she could tear them into bits or else just cram the whole slice into her mouth. Hard boiled egg, cold pasta, babybel cheese, coctail sausages are just some things I used to give her.
