I would try to get her fed before she is "really tired, or we're in a hurry"--which can be challenging sometimes, but much easier in the long run. Also, most kids are ready to feed themselves finger food at this age. I know my daughter LOVED canned carrots, green beans, peas, which were all soft enough for her to eat well on her own.
I also realized my husband and I were SO much happier when we accepted the fact that meal times were also going to become "messy" times now that she's feeding herself. We got her these great long-sleeved bibs from IKEA (2 for $5) and let her go at it! The toddler cutlery (spoons and forks) have been very fun to watch her try, emphasis on try, to use. She feeds herself yogurt, dry cereal, rotini pasta and other things using her "fork".
