This is the easiest pasta sauce, using just three ingredients. My kids love it!
Cook pasta until al dente. Reserve ½ cup pasta cooking liquid. Drain pasta.
Meanwhile, heat olive oil and tomato paste over medium heat for one minute. Turn heat down to medium-low and cook 4-5 minutes to caramelize tomato paste and deepen the flavors. Do not burn. Add garlic and cook another minute until lightly browned. Add ¼ cup of pasta cooking liquid to tomato paste sauce and stir well. Add a little more pasta cooking liquid if a thinner sauce is desired.
Toss pasta with tomato sauce. Garnish with basil chiffonade. Serve immediately.
