1. Set a pan on high heat and spray with cooking spray. Place mushrooms on top in a single layer, sprinkle with some salt, and spray again. Let them cook without moving them for three to five minutes. Any water from the mushroom should dry out at this point. Shake the pan or turn the mushrooms over. They should be browned and toasted on one side. Allow to cook for another three to five minutes, sprinkling with the garlic, salt, and thyme in the last minute. Shake the pan to distribute the spices. Once the mushrooms are toasted on both sides, remove from the pan.
2. Immediately add the sunflower seeds to the hot pan, watching it carefully for two to three minutes, shaking the pan every once in a while. Remove the seeds from the pan when they turn golden and toasty.
3. Place all the dressing ingredients into a bowl. Use an
immersion blender to blend until everything is combined.
4. To assemble, place the sprouts, shallots, peppers, and avocado in a bowl. Top with the toasted mushrooms and seeds. Toss with dressing and serve.
