Thaw the edamame by either boiling in a pot of water for 1 minute or running under hot water in a colander for a couple minutes. Drain and set aside.: The edamame should be warm and vibrant when ready, with a faint beany aroma and slightly firm bite, not mushy. Why this matters, I find that quick blanching wakes up the frozen beans and removes any freezer taste, while running hot water is faster and nearly as effective. A common mistake is leaving them submerged too long, which can make them waterlogged and dull the texture. Drain thoroughly so excess water does not dilute the dressing when tossed with the vegetables.
In a large bowl, combine the edamame, shredded cabbage, carrots, red pepper, and green onions. Leave the toasted almonds to the side for garnishing at the end.: When combined, you want a riot of color and a crunchy, layered texture, with the sharp green onion threads peeking through. The reason I toss the raw ingredients first is to have a single place to pour the dressing and toss uniformly. Avoid overdressing at this stage if you plan to hold the salad for later, otherwise the cabbage will soften; instead, dress right before serving for maximum snap.
Make the spicy sesame dressing. In a medium bowl, combine the tahini, avocado oil, toasted sesame oil, maple syrup, chili paste, rice vinegar, lime juice, garlic, ginger, salt, pepper, and water. Whisk to combine. The dressing should be thick but pourable. Add more water if necessary and then set aside.: A well emulsified dressing will look glossy and cling to the spoon, releasing small ribbons when poured. The aroma should be nutty with floral sesame notes and a hit of chili heat. The purpose of whisking gradually and adding water slowly is to avoid breaking the emulsion. A typical pitfall is adding too much liquid at once which thins the dressing beyond use; fixable by adding a touch more tahini or whisking vigorously to re-emulsify.
Prepare the mushrooms. In a small bowl, combine the Tamari, maple syrup, and sesame oil. Set aside.: This simple marinade reads salty, sweet, and nutty when smelled, and it will become the glaze that finishes the mushrooms. The reason for mixing it separately is to add it toward the end of sautéing so it reduces quickly and clings to the mushroom surfaces. Be careful not to add too much early, because the sugars in the maple can burn if exposed to high heat for too long.
Heat a large skillet over medium-high heat. Add the oil to the skillet and swirl around. Add the mushrooms all at once and let them sit for a full minute. Give them a stir and then let them sit for another full minute. Season with salt and pepper. Keep sautéing the mushrooms until they are tender, golden on the edges, and all excess liquid has cooked out, about 5 minutes. Add the Tamari, maple and sesame oil mixture and stir for another minute. Stir in the sesame seeds and remove from the heat.: The pan will vocalize this step with a sizzle as the mushrooms hit the hot oil, and you should smell a deepening roast as they brown. Letting mushrooms sit undisturbed encourages caramelization, creating those golden edges that add texture and richness. The why is simple, rendered moisture must evaporate to concentrate flavor, otherwise they steam and become rubbery. A frequent error is overcrowding the pan, which traps moisture and prevents browning; if that happens, cook in batches to achieve the correct Maillard reaction.
Assemble the salad. Pour the spicy sesame dressing over the cabbage and other vegetables. Season with salt and pepper and toss until everything is coated evenly. Top the spicy sesame slaw with the mushrooms and toasted sliced almonds. Enjoy!: As the dressing coats the shredded cabbage and carrot , the bowl will take on a glossy sheen and a fragrant sesame aroma. Tossing ensures each strand gets flavor, and the final scatter of warm mushrooms adds a contrasting temperature and savory depth. The crunchy almonds give an audible bite with each forkful. One mistake to avoid is tossing until the almonds are added; they should be reserved until the end to stay crisp. Taste for balance, and add a squeeze of lime or a pinch of salt if it needs to brighten before serving.
