Just keep offering them!! Kid's taste buds are much more sensitive to new flavors than adult ones are, so things taste much stronger to them.
But you have to really offer new foods continuously, not just a few times. Offer tiny portions, so you're not wasting too much food, and try to offer things that 'go together' like mashed potatoes with some cheese, or broccoli with cheese sauce or mac and cheese with a little ham and broccoli cut up and cooked with it. Take a slice of turkey and roll it up with some shredded carrots, lettuce and a piece of cheese in the middle and make a 'roll up' - more fun than a regular sandwich.
I would NOT recommend 'hiding' the food or trying to disguise it as something else. Then you just teach that it is icky and needs to be 'hidden'. Just keep offering, offering, offering- and make sure you eat it yourself in front of her and give a big YUM YUM everytime you do it! She will want to copy you and eat 'grown up' food eventually. Some things she may turn out to not like- but she needs to really have tried to eat things enough to actually KNOW that.
We always gave my son a very small portion of EVERYTHING we ate- no exceptions. He had to at least TRY one bite of each thing on his plate, and did not get any seconds on things he did like until he had tried everything. He didn't always want to, but in the end he did.
Now, my son will eat almost anything- loves sushi, thai food, curry, all sorts of things. But he will NOT eat cheese cubes or a slice of cheese on a sandwich! It is really the only thing he won't eat, lol. He will eat mac and cheese, grilled cheese sandwiches, greek yogurt (which is more 'sour' tasting than american sweetened yogurt) and ravioli or cheese pizza- but not a piece of cheese.
We tried a LOT of different cheeses and tastes before we reached an agreement that he just doesn't like that now. He is almost 10, and since he eats everything else, including veggies with no problems, I don't worry about it. But he always had to try everything on his plate and eat at least one bite of it, when he was small. Good luck!
