This is great for a last minute appetizer and is extremely versatile. Change up the veggies, spices, and herbs and you have another great appetizer. I used Pillsbury crescent rolls (yes, they're vegan) and I actually like them as a crust a bit more than puff pastry (which is also vegan). The crescent rolls have a fluffy layer effect that's light and tasty. I cut the tart into 9 squares, but feel free to slice and dice the way you'd like.
