What To Do:
1. Fill a medium pot half way with salted water and bring to a boil. Cut lemon in half. Roughly chop parsley.
2. Cook Pasta: Add pasta to the boiling water and cook until al dente (about 6 minutes). Drain, reserving ½ cup pasta water. Set aside.
3. Cook Aromatics: While pasta is cooking, place a high-sided large sauté pan over medium heat. Add 2 tablespoons olive oil, shallots, garlic, only ½ teaspoon dried oregano (save the rest for another use), red pepper flake, ½ teaspoon salt and ¼ teaspoon pepper. Cook stirring for 3 minutes.
4. Cook Tomatoes: Stir in tomatoes and cook stirring occasionally until tomatoes are just beginning to split.
