Look at choosemyplate.gov - it's the USDA nutrition site. And it is HUGELY important for her to learn to like veggies now. ALL the scientific research supports that our lifelong eating habits and acceptance of new tastes are established early. (of course there are people who are exceptions). DS as a toddler ate steamed carrots, broccoli, peppers, peas, cucumber (you can grate it and mix with yogurt and a little cumin), avocado, yams (roasted, baked or pureed), edamame (smash them a little), cauliflower, corn, seaweed salad (LOVED this), steamed green beans (also dry fried Sezchuan style), beets (roasted, any way they are on a restaurant menu - I don't eat them so we will order them for him). We added artichokes and fresh green peppers when he had teeth (still loves them).
Children need to try foods an average of 12 times before making a long term decision about whether they will consistently eat them. Keep trying. Kids like foods that are used as a reward more (if you offer an edamame if she sings a song or something like that she will like it) and like foods less that they are rewarded for eating (if you offer a cookie if she eats her broccoli it decreases her liking of broccoli and increases her liking of cookies). We stayed away from any rewards around food.
Hiding vegetables does get them into the kid. But the research shows it does not increase a child's likelihood to eat that vegetable again. And a lot of this is about teaching kids to like and choose healthy options later on.
