Roasting veggies makes them sweeter, also the spice mixture can help as well, I cut up different veggies and drizzle with olive oil then some spice mixture, then roast for about 17 mins, we have one called brown sugar bourbon, you might like that, or something with sesame.
There is a type of squash in season now called delicata you might like.
If you eat salad, maybe try a sweeter dressing...
Best of luck
