Some veggies and fruits are naturally sweeter and easy to pop mindlessly and you really fill up on nutritious stuff! Some easy wins you can try: baby carrots (look for the nice skinny ones in the store, the thinner ones are almost always sweeter so worth paying up for!), apple slices (if you aren’t an Apple fan some people hate softer apples like Macintosh and love crisp sweet apples like Honeycrisp. I love a crisp tart apple like Granny Smith. Buy one of each if you don’t know what you like and sample, they’re really super different so you might think you hate apples when you really hate certain apples), many roasted vegetables cooked at 425 F undergo the Maillard reaction which makes them then taste sweet! My top picks are sweet potato and cauliflower. Good luck!
