Preheat the oven to 400F.
Make the dressing first. Combine all the ingredients and let them sit for about 5 minutes so the cranberries can soften. Add the dressing to a small blender and blend until smooth, this will take some time. Blend for 3-4 minutes or until there are no cranberry chunks left, and the dressing is one smooth pink color.
Tear up the sourdough and place it on a parchment lined baking sheet. Add the pine nuts and drizzle both with olive oil. Roast at 400F for 5-7 minutes or until golden brown.
Assemble the salad while the bread and nuts are roasting. Toss the radicchio, pear, and radishes into a large bowl. Coat with the dressing and toss well. When the bread is out of the oven, add it to the bowl and toss again.
Now it is time to plate the salad. Add a large smear of ricotta to each plate, then sprinkle on the pine nuts. Add the salad on top.
Use your hands to tear up the tender herbs to activate the aromatics. Use these to garnish the salad, then serve!
