Some restaurants have kept their kitchens open amid the coronavirus pandemic, but now more chefs are sharing their best kept culinary secrets so people can recreate their popular menu items right at home.

"Good Morning America" checked in with Chef Telmo Faria from his San Francisco restaurant, Uma Casa, which is known for its delicious and authentic Portuguese fare.

Since the coronavirus outbreak halted normal restaurant operations, Faria has spent time working with food organizations to prepare meals for front-line workers as well as donating basic items like yeast and flour to those who need it.

"I've shipped yeast and kosher salt as far as Florida," he said.

Uma Casa has continued its kitchen operations to fulfill take-out orders and Faria said the most popular item on the menu is his piri piri grilled chicken.

"We have a chicken that has been cut in half. For the marinade we are going to use some white wine, this is a Portuguese white wine, but you can use any dry white wine, we have a little bit of red wine vinegar, some bay leaves, some garlic cloves," he said of the staple ingredients for the dish.

The homemade Portuguese spice mix includes "a little bit of cumin, coriander, clove, and little bit of ground pepper as well, then just some kosher salt," he said.

Due to demand, Uma Casa is launching a virtual online cooking class for the Piri Piri chicken dish. The restaurant says that a portion of the class proceeds will be donated to organizations that feed front-line workers. Click here to learn more.
