+## 7.0 Tomato Soup
+
+There are few things that scream “home” and “comfort”as much as a bowl of creamy tomato soup served with a grilled cheese sandwich. The simple meal consists of ingredients we all have in our homes so it’s the kind of recipe I turn to often. Whether as a simple lunch for the kids or a family dinner, grilled cheese and tomato soup is the answer. Perfect for feeding a crowd and exactly what I’m craving when the weather is on the cooler side.
