[Vegetarian] Do you guys have any suggestions to make this taste better?

So, my go to meal is a really simple sauté dish, and I was wondering if you have any spice or vegetable recommendations for this dish. It's first:

Olive oil, and coconut aminos

Red onion, and a lot of spinach

Then broccoli and zucchini on top, and possibly some more olive oil.

So if you've got any recommendations to add to my dish to make it taste better or be healthier, it'd be greatly appreciated!
