I have kids aged 12, 7, and 5. All of them like some SB stuff, but none of them like the exact same SB stuff. So it's a trial!

but we're working on it.
They all love baked goods like muffins and cookies that I make with whole grains and Splenda. While I wouldn't feed other artificial sweeteners to my kids, I believe Splenda is safe. Alternatively, sometimes I bake using agave syrup, or a fruit base + stevia, or honey. There are differences of opinion amongst my kids as to how acceptable any of these other sweeteners are. Often I sneak a bit of ground flaxseed or soy protein powder into the baked goods.
2 out of 3 love sweet potatoes cut in fry-form, then tossed in a bit of olive oil and chili powder and baked until chewy-crispy.
They all love to have salmon-salad sandwiches on whole-wheat bread. We buy canned salmon in place of tuna for them to avoid mercury.
Fresh fruit favorites include apples, grapefruit, cherries, strawberries, oranges, tangerines, kiwi...it varies from child to child. I try to always have some fruit around that each of them will eat.
2 out of 3 enjoy pomegranate juice. We're not really big on juice at my household, but I should probably get some calcium-fortified OJ for them.
Occasionally they have fat-free hot dogs (made from beef or turkey) on buns containing whole grains for lunch or dinner. All 3 enjoy this. The oldest one enthusiastically eats a sugarfree veggie relish that I make for hot dogs.
All of them like nuts at various times. We usually have peanuts and others around for snacks.
I let them eat shredded wheat cereal by the handful for snacks instead of crackers. All it's got in it is just whole wheat, but the crunch is very satisfying. Or sometimes they eat Cheerios as a snack--Cheerios have some sugar, but it's not much.
All 3 enjoy milk at various times, usually when eating one of my cookies or muffins.
Burritos made with refried beans, cheese, and a tortilla. Super-easy, very tasty and nutritious. 2 out of 3 like these. Ditto nachos which are simply refried beans, little bit of cheese, tortilla chips--maybe some lean ground turkey and onions and garlic if it's a dinner meal. Oldest will eat with salsa, which is very nutritious.
It's not all that hard (from an intellectual standpoint) to feed kids the SB way, but it is a little more time-consuming in preparation and planning. And certainly you will have some fights with them over it; but that's kind of the fate of a mom, to be the "heavy" on food. My kids really appreciate and participate actively in explanations and discussion about nutrition and health.
