personally i think that about 95% of the time you can find a middle ground where you're not making two totally separate meals. granted, i grew up being that picky person being somewhat catered to, so i might have a skewed view.
i mean if you're making chicken and broccoli and mashed potatoes, that's doable for everyone. the pickies should be able to take the chicken being baked and you can add spices to your portion if you prefer. make the potatoes plain, just adding in milk or greek yogurt and a little pepper and salt. if they want bacon or butter or anything else they can add it to their portion, not the pot. steam the broccoli and if they want butter or mayo or something else, they can add it to their portion at the table.
if you're talking about a pasta dish, you could do the whole pot light to your taste, remove a portion or two for you [tonight's dinner and tomorrow's lunch], then add a second light portion of the heavier stuff to their tastes.
personal pizzas are as easy as a big pizza for everyone, plus everyone gets their favorite toppings. tacos, baked potatoes, burritos, all of these are good build your own foods.
and it's easy to partially offset a heavier meal with a salad.
i mean, what foods do they love that you can't have? working on lightening up those is going to make your life easier.
