Find a way to change those foods into something you're comfortable with.
Textures are extremely easy to deal with. You can make soups, chopped salads, sauces, mashes, you can cook for longer, or even cook so long that it completely breaks down. There's so much cooking information online about how to change stuff up, that you just need to take some time and look up some recipes.
Flavors are also easy to deal with. Roasting vegetables is a game changer in terms of taste, and you can even use them as ingredients in other recipes or meals.
Meal prep and freeze. It's a lot easier to make a lot of something and store/freeze it for later.
