Mix the tahini sauce ingredients together with a fork until creamy. Taste, then adjust ingredient amounts to your liking, adding more water to thin if necessary. Set aside.
Heat a medium-large nonstick skillet over medium-low heat. Add the oil then saute the zucchini for two minutes, stirring occasionally.
Add the peppers, then saute two minutes.
Fold in the artichokes, sun-dried tomatoes, and olives, stirring and cooking one minute more.
Reduce the heat to low, then fold in the chickpeas, diced vine tomato, lemon juice, dried oregano, salt and pepper. Cook until warm.
Meanwhile, heat the two tortillas in a large dry skillet until warm and pliable.
Spread 2 tablespoons of hummus evenly over each tortilla, followed by a handful of fresh baby spinach.
Divide the filling between the two tortillas, then top with the vegan feta and tahini sauce. Enjoy!
