Melt butter in a large saucepan over medium-high heat. Add onion, 1 tablespoon sage, and garlic to pan; saute 4 minutes or until lightly browned. Add pepper and cumin, saute one minute.
Stir in 1/2 cup stock; cook 1 minute, scraping pan to loosen browned bits. Combine onion mixture, remaining 2 cups stock, beans, and pumpkin in a blender jar.
For Vitamix: Turn machine on and slowly increase speed to Variable 10 or use the soup setting. Blend until smooth, then add milk and salt. Blend for 6-7 minutes or until heavy steam escapes from vented lid.
For Blendtec: Run the SOUPS cycle one time. Then add milk and salt and run the SOUPS cycle two more times, until heavy steam escapes from vented lid.
For either blender, add vinegar and use Speed 1 for 5 seconds or pulse a few times to quickly combine.
At this point you can save the soup for later! If serving immediately, then rinse out your blender jar and carry on with the pesto.
For Pesto
Combine remaining 1 tablespoon sage, spinach, and remaining ingredients in your blender jar (use a smaller jar than the 64 oz container if you have one).
For Blendtec: Use speed 6, let it run between 15 and 30 seconds. Careful not to over blend! Keep it a bit chunky.
For Vitamix: Start on speed 1 and slowly increase to speed 7 and let it run for 30 to 45 seconds. Press the ingredients into the blade with the tamper.
To Serve
Ladle about 2/3 cup of bisque into eight bowls; top each serving with 2 tsp pesto.
