It can be so hard. I agree to throw out the noodles and chips. Make your own chips. My ds is 17 months and was really really really fussy to begin with and i was going nuts. He still can be difficult when tired. If he hasn't slept well or is unwell then I stick with things I know he loves.
What i do now is have a tasting plate of a few different things. Include one new thing every few days along with stuff he does like so it's not a totally foreign meal for him. So for lunch on one plate there might be 3 things i know he will eat plus one new item. And yes you do need to offer it again and again and again! Don't be disheartened if it doesn't work. Persist.
I also think it's important to eat together. Sit down and have fun with your food. If she sees mummy really enjoying her lunch or dinner then she might want to join in? Let her have a bite from your plate. Is she interested in watching you cook and 'help'? I offer tidbits of what I'm cooking to ds as I'm chopping it up and he likes to watch me prepare food. Get her involved.
At the end of the day it's most important to keep mealtimes battle free. If she's refusing to eat what you've made then clear it away and say "lunch is over". No emotion.
The "one handed cooks" website is a really good source of information on this topic. I highly recommended you check it out.
