Microwave Pizza Sauce
Place bowl with tomato juices in microwave and cook on high until pizza sauce or ketchup thick, about 20 to 25 minutes. Add crushed tomatoes to sauce. Cool to room temperature.
Flavor the sauce any way you like and use it on pizza, pasta or to thicken soups and sauces.
Recommended technique: All canned tomatoes are not created equal. Make sure they have no added sugar, fat or sodium. To find the best tasting brand, buy two different brands at a time and do side by side comparisons. Keep taste testing until you've come across one you love. Muir Glenn and Progresso brands are consistently good, but you be the judge.
