In a blender, combine the grated Parmesan cheese, miso paste, lemon juice, garlic, olive oil and mustard. Blend until mixed and then add water as needed to thin down dressing. Remove kale from stems and place in large bowl. Add dressing and massage into kale with both hands until kale wilts and shrinks down. Brush olive oil onto bread slices and season with salt and pepper (or seasoning salt). Toast bread and then slice into squares. Add salad to bowls and top with croutons and Parmesan shavings.
