Toss eggplant slices with 1 tbsp olive oil and salt.
Repeat with bell peppers and zucchini using another tbsp olive oil.
Sprinkle veggies with oregano, paprika, salt, and pepper.
Preheat a cast-iron skillet or grill pan over medium-high heat for 3–4 minutes.
Cook eggplant for 3–5 mins per side, zucchini for 2–3 mins per side, and bell pepper for 3–4 mins per side.
Cool veggies completely.
Blend chickpeas, tahini, salt, water, and lemon juice until smooth. Adjust seasoning if needed.
Spread 1/4 cup hummus onto the lower third of a tortilla.
Layer zucchini and eggplant slices, top with bell pepper.
Fold bottom of tortilla over veggies, fold in sides, and roll tightly, seam-side down.
For a crispier wrap, grill in a pan with cooking spray, butter, or remaining oil.
