Forcing to eat as is has been proven to be the wrong approach.
My son has grown up on the three try - 2 tablespoon rule. He tries it on three occasions, never more than 2 tablespoons being required. If he doesn't like it, he doesn't like it.
He has a much broader range of likes and healthier diet than I do, as he is always willing to try new foods and be the first to tell you it sucks if he believes that it does. Chopped tomatoes are not on his list of likes, he eats around them (as do I). We both will have small piles of tomatoes left on the plate, however mine will also have small piles of other foods thanks to a parent who required me to eat foods I could not stand.
No one should be required to eat something they don't like. That is why we have taste buds to begin with and why we are designed to also enjoy or not enjoy textures.
