Prepare the pickled radishes at least a day before you want to serve this recipe. Add the Dandy Radish Mini Sticks to a large jar or other glass container. Add the vinegar, water, maple, sea salt, peppercorns and red pepper flakes. stir briskly. Cover jar and place in the fridge to chill for at least eight hours, and overnight is even better. The longer the radishes chill and marinate the more flavor will emerge. The color of the radishes will fade a bit into a light pink, but the pickled texture is amazing! Perfect for topping salads and sandwiches like this recipe.
Day of serving. Prepare your pea spread. If using peas in their pod, remove them from their pods, until you have about ¾ cup. Bring a small pot of water to a boil and submerge the peas for about 2-3 minutes, or until they darken in color and soften. Once they are tender, strain them from the water and rinse them in cold water or an ice bath to preserve the green color.
Place the peas, avocado, walnuts, lemon juice, olive oil and optional garlic clove in a blender or food processor. Blend from low to high until smooth. Add the salt and pepper to taste. Salt (and the lemon juice) are important for bringing out the savory flavors in the spread. Pour the pea-avocado spread into a small bowl.
Slice your bread and lightly toast. Rinse and dry your fresh sprouts.
Slather 2-3 tablespoon of the pea-avocado spread onto each slice of bread - add a generous amount for a think layer of spread. Then top with as many pickled radishes and fresh sprouts as you'd like. Finish with some fresh black pepper on top. If desired, you can add a pinch of fleur de sel or another coarse sea salt on top to serve. Slice and serve the toasts. Best served same day.
