By request, my favorite pasta recipes for the hungry and time-pressed.
Spinach Penne with Ricotta
This is from the De Cecco pasta box, but I like it anyway.
Cook whatever amount of pasta seems appropriate for one person. After cooking, drain and then add the pasta to a bowl with 2 large forkfuls of part-skim ricotta, 1 tbsp butter, 1/2 tsp -ish of fleur de sel, and a generous shaking of crushed red pepper. Mix until coated.
You can use whole-milk ricotta if you keep the pasta a bit wet when you drain it (or save a spoonful of pasta water) and leave out the butter.
Simple Pasta with Sausage & Cheese
Cook Italian sausage in a non-stick pan until browned, adding spices as desired. I generally add more fennel, oregano, basil, black pepper, and salt. Once sausage is mostly cooked, boil water and cook some pasta (I like farfalle). Grate copious amounts of hard Italian cheese. Drain pasta well and add to pan with sausage. Toss until delicious sausage fat has coated the pasta. Turn off heat and add cheese. Toss. Eat.
