This is going to sound crazy, but....

I personally don't know a fruit or vegetable I won't eat, but I can't stand ANY kind of seafood so I'm with you there.
Jerry Seinfeld's wife wrote a book about putting healthy fruits and vegetables into food for kids. I know it's aimed at tricking kids into eating veggies, but maybe it would work for you too since it changes the textures of these foods when you add them to other stuff.

Just an idea GL!

Don't sweat the fruits and veggies. Focus on the healthy foods that you do like. Do you like potatoes, legumes, or whole grains? Potatoes are full of nutrients and have a good balance of protein and fat. One of my daughters didn't like any fruits or vegetables either. She is now 7 and will suck on a lemon and likes lemon-flavored things, but she won't eat one. She likes olives, which are technically a fruit. This past year, she has learned to like corn on the cob and of all things, artichokes. Guess what we eat every week. She likes salsa, so I buy her baked corn chips for dipping.

Since you like spaghetti sauce, like my daughter, I would eat a lot of that, but seek out healthier brands or homemade. You don't need a lot of variety in your diet to be healthy. In fact, statistics indicate that a simpler diet aids weight loss. As opportunities, arise, try new things, but don't beat yourself up over what you don't like. Don't be miserable trying to do what everyone else tells you to do.
