Bring a large covered pot of salted water to a rolling boil.
Meanwhile, grate the tomatoes into a large sauté pan with a coarse grater.
When the pasta water comes to a boil, cook the pasta in the salted water, stirring occasionally, until al dente, tender yet still firm to the bite.
Meanwhile, cook the grated tomatoes, uncovered over medium low heat, stirring occasionally, for about 10 minutes, or until all water is evaporated.
Stir in the olive oil and salt. If using almond flour, stir it in now, which will make the sauce creamy. Turn off the heat.
Drain the pasta, and stir it into the sauce. (Drizzle in a little more extra virgin olive oil, if you've got the good stuff.) Taste and adjust for salt. Then, gently stir in the basil.
Optional: To serve, sprinkle with almond flour, if using, or the grated or crumbled cheese of your choice.Enjoy! Buon appetito!
Notes
Tomatoes: Some tomatoes are better for sauce than others. In Italy, generally any of the non-round varieties are favored.
Great Cheese Options for Topping: freshly grated Parmigiano Reggiano, grated ricotta salata (hard salted ricotta), crumbled feta cheese, or globs of stracchino
