01 - Combine chickpeas, baby spinach, garlic, tahini, lemon juice, olive oil, cumin, and salt in a food processor. Blend until smooth, scraping down the sides as needed. Gradually add cold water, one tablespoon at a time, until a creamy, spreadable consistency is reached.
02 - Lay each whole wheat tortilla flat on a clean work surface. Spread 2 to 3 tablespoons of the spinach hummus evenly across each tortilla, leaving a small border around the edges to prevent overflow when rolling.
03 - Arrange shredded carrots, sliced red bell pepper, cucumber, red onion, and avocado in a horizontal line across the center of each tortilla. Drizzle with yogurt if using, and sprinkle chopped parsley or cilantro over the vegetables.
04 - Fold the left and right sides of each tortilla inward over the filling. Starting from the bottom edge, roll the tortilla up tightly toward the top. Slice each wrap in half on a diagonal and serve immediately, or wrap tightly in parchment paper for a portable meal.
