Pasta alla Matriciana

In a medium saucepan, cook bacon or pancetta over medium heat until golden brown, about 10 minutes. Add garlic, onion and red pepper flakes; cook about 3 minutes, stirring occasionally. Add tomatoes and bring to a boil. Reduce heat to medium-low and cook uncovered 30 to 40 minutes, stirring occasionally.

Bring a large pot of water to boil; add salt and pasta. Boil 8 to 10 minutes or until pasta is al dente. Drain pasta, add sauce and serve with Romano cheese.
