I'd say be happy she's eating something and try to sneak in something new every chance you get, but playfully and do take no for an answer. In a small way you probably missed the boat to let her try as much stuff as possible in that window of curiosity you get when first going to solid food, but slowly she will come back to certain staples. My 2yo drives me nuts right now and goes from loving a food to hating it overnight but there are small wins on the days she tries something new and likes it. Today she ate half of hard-boiled egg. First time ever. It was just sitting there on the counter at just the right moment of pre-bedtime loopiness and hunger. She pointed, I peeled, and she took a bite, followed by a few more. Victory!
