1. For the Mushroom Confit, place shallot, garlic, fresh herbs, coriander, peppercorns, cloves, bay leaves and star anise in center of double layer of cheesecloth. Wrap to enclose, tying tightly with butcher twine. Set aside.
2. Heat large heavy-bottom saucepan on medium-high heat. Brush mushrooms lightly with oil. Sear mushrooms on each side just until lightly browned, about 30 seconds per side. Reduce heat to low; sprinkle evenly with salt.
3. Add oil and herb sachet to saucepan (oil should cover mushrooms). Heat on medium heat until temperature reaches about 180°F (80°C) on an instant read thermometer (this should take about 10 minutes). Reduce heat to low. Cook 25 minutes. Stir in vinegar; cook 5 minutes longer. Remove from heat. Use a slotted spoon to remove mushrooms from oil. Reserve oil for another use. Set mushrooms aside, keeping warm until ready to serve.
4. Meanwhile, for the Citrus Aioli, whisk all ingredients in small bowl until well blended. Cover and refrigerate until ready to serve.
5. To assemble Bánh Mì, split rolls lengthwise, being careful not to cut all the way through. Spread rolls evenly with Citrus Aioli. Layer baguette with carrot, cucumber and mixed greens. Spoon Confit Mushrooms onto rolls, draining any excess oil. Top with sliced chili, green onion and cilantro to serve.
