Toss the sliced bacon into a large saucepan and cook over medium heat. Slowly render the bacon until the grease is released and the bits get crunchy (about 10 to 15 minutes). Transfer the crunchy bacon bits to a paper towel lined platter and set aside.
Add the Italian sausage to the bacon grease and cook, breaking it up, until it is no longer pink. Use a slotted spoon to transfer the cooked sausage to another plate.
Remove all the oil except for 2 tablespoons. Toss in the chopped onion, along with a sprinkle of salt. Cook, stirring occasionally, until the onions are softened, about 8 to 10 minutes.
Stir in the minced garlic and cook until fragrant. Add the potatoes and pour in the chicken broth. Increase the heat to high to bring the broth to a boil.
Add the kale to the soup and decrease the heat to maintain a simmer. Continue simmering the soup until the potatoes are fork-tender and the kale is softened, about 10 minutes.
When the vegetables are ready, return the cooked pork sausage to the pot.
Pour the cashew cream into the soup and stir well to combine.
Taste for seasoning and some freshly cracked black pepper and add more salt if needed. Stir in the lemon juice. Taste and add more lemon juice, if needed.
Ladle into bowls and top with crispy bacon bits. Enjoy!
