How to Make Crab Banh Mi Rolls
Combine the Mayo: In a small bowl, stir together veganaise, whole grain mustard, and fish sauce until smooth. Taste and adjust the seasoning as needed, then refrigerate for at least 30 minutes to let the flavors meld.
Make the Slaw Dressing: In another bowl, whisk together extra virgin olive oil, ume plum vinegar, water, and freshly ground black pepper until well mixed. This dressing will elevate the radish and chili pepper mixture with its zesty notes.
Prepare the Slaw: Drizzle the slaw dressing over the sliced watermelon radish and red jalapeño. Toss until everything is coated evenly. The colors should be vibrant, and the mixture will start to shine!
Add Fresh Herbs: Gently fold in the coarsely chopped cilantro, torn mint leaves, and chopped chives into the radish mixture. Set aside for the flavors to mingle while you prepare the buns.
Toast the Buns: Preheat your skillet or toaster until hot, then toast the brioche buns until they re golden brown and slightly crisp on the outside. This will add a lovely texture to each bite!
Assemble the Sandwiches: Spread a generous layer of umami mayo on each half of the toasted brioche. Place a fresh gem lettuce leaf on each half, then layer a heap of the radish slaw and snow crab meat on the bottom half. Finish by topping with the other half of the bun to create a satisfying sandwich.
Optional: Add a squeeze of lime juice for an extra zing!

Tips for the Best Crab Banh Mi Rolls
Mayo Magic: Ensure your mayo ingredients are well combined for creaminess. Let it chill to intensify flavors; this umami mayo is your secret weapon!
Slice with Care: Use a sharp knife to thinly slice the watermelon radish and jalapeño. This prevents uneven pieces that can affect the crunch and flavor of the slaw.
Toast Those Buns: Don t rush the bun toasting! A golden, slightly crisp exterior adds texture and prevents sogginess when loaded with juicy crab and slaw.
Herb Harmony: Mix the herbs gently into the slaw. A light hand preserves their fresh flavor and prevents bruising, allowing each bite to burst with freshness.
Adjust to Taste: Feel free to tweak the heat and acidity in the slaw dressing based on your preference. Adding more (or less) chili or ume plum vinegar can transform your Crab Banh Mi Rolls!
