Toddler food advice

Lexie

So my toddler is a picky eater well that’s what I think, she will he turning 2 in December and I still give her 2 bottle of formula due to the lack of food she doesn’t eat she refuses to eat any type of meat and if she does eat meat, it’s chicken from Taco Bell and sometimes beef brisket, and If I do find something she likes to eat one day she will not eat it the next day, I tired everything I possibly can to give her the problem and nutrients she needs, the only thing she loves to eat everyday is sweet peas, apples, berry fruit bars, veggie chips,watermelon,goldfish,pasta, and spaghetti.I need some advice what can I give her to eat the stuff she needs so I can stop buying formula, her doctor said to keeep giving her formula till she eats 3 times a day and she only eats 1 or 2 times a day and snack throughout the day, but she going to be 2 soon so I wanted to get her off, I do give her one bottle of oat milk due to stomachache she been having since birth. But she refuses to eat breakfast besides a bottle and she sometimes refuses to eat dinner and just throws it in the grown even if she likes it so I ran out of options, she doesn’t like peanut butter, some meats, quesadillas,soup, or anything you can possibly make easy for w toddler has this ever happened to anyone else I need some advice!
