Toss cauliflower with a little olive oil, salt & pepper and roast on a baking sheet for 30 minutes (or until golden brown)
Prepare your shells and cheese (according to the box), or make your sauce and cook your shells. Mix together, adding enough almond milk to make it creamy.
To your pot of mac & cheese (while it's still hot), add chopped jalapeños, kale and stir until the kale wilts. Stir in the roasted cauliflower, and a grating of fontina cheese if you like. Season with salt & pepper.
