Toddler bad eating habit

Has anyone ever had this problem? I’ll fix dinner & we both have the same exact thing on our plates but she throws a fit for my food. There will be days I fix her a whole breakfast meal & wouldn’t touch it & I get something small like hot dogs with ketchup, which she doesn’t like, & she’ll throw a tantrum because I wouldn’t give it to her & when I’ve had enough & finally let her have it she takes one bite realizes what it is & doesn’t want it. I literally have to eat in another room or wait till she’s asleep to eat in peace. I don’t know what to do anymore! It’s so frustrating.

Edit: Shes turned 2 in December. Idk if age has anything to do with it.
