Preheat oven to 325 degrees F.
On a baking sheet lined with aluminum foil for easy cleanup, toss eggplant, zucchini, garlic, and onion with olive oil and season with salt and pepper. Roast vegetables for about 30 to 40 minutes until tender, being sure to monitor so they don't burn. Remove from oven and let cool to room temperature.
While the vegetables are in the oven, make the chutney. Heat the grapeseed oil over medium-high heat in a small saucepan until it begins to shimmer. Add the shallot and saute until it begins to turn translucent, being careful not to burn it. Add the orange juice, balsamic vinegar, mango, and parsley, and allow the liquid to reduce by 2/3. Season with salt and pepper, stir in slurry to thicken and let cook for about 2 minutes, then remove from heat.
Add the garbanzo beans, garlic, crushed red pepper, lemon juice, tahini, and olive oil to a food processor. Pulse to combine and coarsely chop.
Heat grapeseed oil over medium heat in a skillet and sear the tofu cubes. Set aside until needed.
Preheat oven to 400 degrees F.
If phyllo was defrosted, make sure it is completely defrosted before handling it. Once removed from package, you will need to cover phyllo with waxed paper and a damp towel to prevent it from drying out. Working with 1 sheet at a time, lay out a dough sheet on a baking sheet and brush on butter, and lay another sheet on top and brush with butter. Fold in half, brush on butter again and fold in half again so you have a thickness of 8 layers. Spread 1 tablespoon hummus on phyllo and top with 1/4 cup of the roasted vegetable mixture and 1 tablespoon diced tofu. Fold in corners of phyllo dough to the center and brush with egg wash. Repeat to make 4 phyllo purses. Place on a baking sheet and bake in oven until golden brown, about 30 minutes.
Remove from oven and serve hot with mango chutney on the side.
