ELI5: Our bodies have adapted to make sugary things taste good since they provide energy. Why hasn't the same thing developed with healthy items like vegetables?

Because vegetables don't provide as much energy as sugars. They are only considered healthy in a modern context of an abundance of food. If you go back several thousand years (an eyeblink in evolutionary terms) finding enough food was a real problem that occupied most of your time. High energy foods like sugary fruits and fatty meats were *way* better than vegetables.
