Step 1
Start by bringing a large pot of salted water to a boil. Toss in the penne and cook it until it’s just tender but still has a little bite, about 11 minutes. While the pasta is cooking, heat some oil in a big skillet over medium-high heat. Add the cauliflower and sauté it for about 3 minutes, stirring occasionally. Then, add the ground beef, chopped onions, and garlic to the skillet. Cook everything together, breaking up the beef with your spoon, until the meat is nicely browned, around 5 to 7 minutes. Next, stir in the canned tomatoes, fresh parsley, a pinch of salt, and some red pepper flakes. Cover the skillet and let it simmer for about 10 minutes so the flavors meld. Once the pasta is done, drain it and toss it right into the skillet with the sauce. Give everything a good mix, then serve up while it’s warm.
