Cook the pasta according to instructions.
Meanwhile chop the spinach and set aside.
Once the pasta is done transfer it to a large bowl and mix with the spinach.
Then bring a medium pot of water to a boil. Add the cauliflower with a pinch of salt and simmer until it's all tender.
Drain the cauliflower and throw it into a blender. Now add the milk, garlic, lemon juice and the olive oil and mix until you get a creamy sauce.
Finally pour the sauce into the pot you boiled the cauliflower in and cook over low heat.
Add the spinach pasta and stir until everything is well combined.
Enjoy!!!!
