To test burgers for doneness, insert an instant read thermometer sideways into the burger. It should register 160° F.
For Marinara Sauce, follow label directions—all you need is 1 can (28 oz/796 ml) each crushed and diced tomatoes, plus 3 tbsp of the blend. Simmer for 15 minutes and you’ll have 6 cups of sauce ready to go! Portion and freeze leftovers.
