Cauliflower Pasta Carbonara

Cook bacon in a large saucepan over medium heat until crisp, 3 to 5 minutes. Remove the bacon to a paper towel-lined plate; discard the bacon fat. Bring 1 inch of water to boil in the same saucepan fitted with a steamer basket. Add cauliflower and garlic; cover and steam until very tender, 10 to 14 minutes.

Meanwhile, bring another large saucepan of water to a boil. Cook spaghetti according to package directions. Drain well. Return the pasta to the pot.

Transfer the cauliflower and garlic to a blender. Add milk, oil, mustard, salt and pepper. Blend until smooth and creamy. Pour the sauce over the pasta. Add peas, Parmesan and the bacon; toss to coat.
