Preheat oven to 350F. Heat a large pan over a medium high flame. Add 1oz of olive oil and 1 garlic clove as it heats, stirring to prevent sticking.
Add the sausage, and brown each side, about 12 minutes. While doing so, put the bread on a sheet pan, divide the remaining garlic and olive oil amongst the slices, and toast in the oven until just brown; remove from the oven.
Add the beans to the pan and stir to incorporate. Lower the heat to medium. Add the Kale to the pan and stir to incorporate. If desired, add about 1oz of crushed red pepper to the pan.
When the kale is bright green, remove the pan from the heat. Divide and serve over crusty toast.
