Wow! I love most fruits so I'm wondering if you've had the opporunity to try many of them, or did you just not like the first couple you tried then gave up? Younger people have more taste buds since they die off as we get older so your tastes may yet change.
I add 10 oz frozen or 1 pint fresh raspberries to 5 oz silken tofu, 1 C apple cider vinegar, and 2 T flax seed then blending to make a salad dressing. It's rather tart and the berries have lots of vitimins and micro nutrients.
If you don't like the sweet fruits, try dried apricots - sometimes they aren't as sweet. Same with citrus like lemons, limes & even some grapefruit. Blueberries too often are more tart than sweet.
Another option is to cook a beef chuck roast with dried fruits and chopped vegetables in water or dry wine. Check out "Tzimmes" in SP recipes. It really doesn't taste sweet but has prunes, apples, pears, & apricots with lots of fiber and mixes into the meat and sauce.
And finally, if you like tomatoes
you're half way there. They are botanically classified as a fruit not a vegetable.
For those with allergies, stay away from strawberries
it's usually the little bitty seeds - and papaya or pineapple
have lots of enzymes which can aid digestion but can also cause irritation.
