Wash kale thoroughly and pat dry. Remove tough stems and tear leaves into bite-sized pieces. Place in a large salad bowl.
Drizzle olive oil and lemon juice over the kale. Add salt and pepper. Using clean hands, massage the kale for 2-3 minutes until leaves become darker green and softer.
If not already toasted, place sliced almonds in a dry skillet over medium-low heat. Toast for 3-5 minutes, stirring frequently until golden and fragrant. Let cool slightly.
Add the toasted almonds and grated Parmesan cheese to the massaged kale.
If using optional ingredients, add them to the salad now.
Toss all ingredients together gently but thoroughly. Taste and adjust seasonings if needed.
Serve immediately for best texture and flavor.
