1 year old not eating enough

my baby has gotten SO picky within this last month. shes almost 14 months and I feel as if shes not eating enough. we just finished lunch and all she ate was 2 strawberries, didn't even touch her pasta. So I gave her some ham and she didn't want that either. idk what to do. Most of the time, she chooses 1 thing on her plate and eats only that. Any advice? She does still eats purees, sometimes. Also, my daughter isn't that good at chewing yet.. how would you offer something new? as in cutting it up?
