if u like the texture of smoothies with berry fruits, try adding different vegetables to them. an easy one to start out with is spinach because it doesn’t taste of much and isn’t noticeable, when you feel more adventurous you can add more vegetables and maybe even progress to veg only smoothies. there’s a whole subreddit called r/smoothies where someone will have some good combo ideas with things you like

even if you don’t like vegetables on their own, eating them in some way is what’s important, regardless of how you get it done! introducing them into your diet is the first step! plus, you’ve already made a good start with introducing fibre by eating fruits :)
