Combine the milk and vinegar and let sit for 5 minutes, until slightly curdled. This is your homemade buttermilk.
Add the buttermilk mixture to the base of a mini blender along with the rest of the ingredients: mayo, ½ avocado, mustard, garlic, parsley, dill, salt and sugar. Puree until creamy, then adjust seasoning as desired. Set aside.
Add the kale to a large bowl along with ½ of the dressing. Using your hands, massage the dressing into the kale for a few minutes. The kale should start to wilt softly as the dressing becomes fully incorporated into the salad.
Add the rest of the ingredients: the corn kernels, remaining cubed avocado, tomatoes, tofu, cheddar, and pumpkin seeds.
Divide into four bowls, then top with the remaining dressing and enjoy!
