We are major Jennifer Garner fans (and not just for her iconic movie and television roles). The actress is equally as passionate about healthy living, cooking and being a mom—and we love watching her culinary ventures on Instagram!

Garner's latest role is starring in her#PretendCookingShow on the social media platform, where she cooks up everything from a weekday breakfast for the kiddos to stunning main dishes for holiday entertaining a la Ina Garten. The latest episode came out earlier in the week and featured a special guest—Daniele Utidi, friend and owner of Pizzana in L.A.—who helped her whip up a restaurant-worthy pizza. And we were seriously intrigued by their hack for homemade tomato sauce.

Uditi grew up in Naples, Italy, where he discovered his passion for cooking at a young age, and eventually brought his skills to the U.S. In this episode of #PretendCookingShow, Uditi shows Garner how to make a super easy and authentic tomato sauce using just two ingredients—San Marzano tomatoes and salt. Garner dumps the tomatoes in a giant bowl and starts mashing them with her hands, sprinkles them with some salt and voila! You have an Italian chef-approved tomato sauce!

"First thing I learned, don't put them in the blender," Garner says. You can tell Uditi runs a tight ship over there.

Now, if you're an Alton Brown fan like we are, you may recognize San Marzano tomatoes from the first episode of Good Eats' return a few weeks ago, featuring chicken Parmesan. Brown noted that, unlike Italy, the U.S. doesn't regulate the authenticity of San Marzano tomatoes, so you have to do a bit of research to make sure you're getting the real thing. We're sure that's crucial for making authentic Italian tomato sauce—especially since this recipe only requires two ingredients.

Once you know which brands to use, Megan Steintrager, digital food editor at EatingWell, says, to look for canned San Marzano tomatoes.

"They're favored by many chefs for their sweet, deep tomato flavor. I love to hand-crush them and use them on a simple Margherita pizza."

We can't wait to try this sauce on our Chopped Salad Pizza with Sausage, Chicken, Tomato & Jalapeno Pizza or even a pie loaded with whatever veggies are leftover in our fridge at the end of the week. And try our Two-Ingredient Dough Margherita Pizza for an impressive dinner that's way easier than it looks. Happy cooking!
