Mom? Is that you?
When my parents made pasta, I would always ask for mine to be "plain." As I grew up, I wanted just a bit of cheese and pepper and olive oil. As I grew up further, I became able to articulate what it was I didn't like! If your children are old enough, try sitting down with them and trying to pinpoint what it is they don't like about the final sauce. Is it really that they don't like the same things you do, or is it just something textural? Something overly or under spiced? It turned out it's the fennel seed in my dad's meat sauce I hate. I can't stand biting into one, because it has that awful licorice flavor and it's also texturally unappealing. I'm almost 30 now, though, so I make my own sauce.
This is one of those challenges like figuring out what sort of pizza to get. In the past, if there are a lot of people with varied tastes, I will simply have a few options. Maybe Jane likes "white" sauce but John likes "red" sauce and mom & dad want meat sauce? From time to time it's not too hard to have a saucepan of each option available. Ultimately, though, you've got to have some peace! Things I've seen in pasta sauces: sun-dried tomatoes, spinach, sweet onion, red onion, sweet sausage, spicy sausage, ground beef, chicken, ground turkey, meatballs, mushrooms, zucchini, eggplant, carrots, spiced & diced tomatoes (these come in a can, pre-seasoned), roasted red peppers, artichokes, peas, anchovies, shrimp, shallots, celery, and corn. You and your child(ren) must have some common ground somewhere in there :)
