Wash zucchini squash, cut off ends, and slice in half lengthwise (repeat the process several times if working with large produce). Chop into bite-sized chunks.
Heat olive oil over medium heat, toss in your squash, and sauté until somewhat tender but still firm to the bite. While sautéing, season well with salt, pepper, and dried oregano. Transfer to a large bowl and leave to cool.
Rinse and drain tomatoes, then cut into halves. Chop feta cheese into small cubes. Slice scallions into rings and tear fresh basil by hand into tiny bits (or finely chop).
Add tomatoes, feta, scallions, and basil to your bowl with zucchini and incorporate well.
Drizzle honey and vinegar over your ingredients and season to taste once more with salt, pepper, and oregano. If needed, add a bit more water or olive oil. Enjoy!
