Simple Tomato Soup


This easy tomato soup is my go-to recipe. It's simple and delicious, ready in 30 minutes, and I give leftovers to my kids for lunch. I usually serve it with rosemary bread for dunking.

Use Italian San Marzano tomatoes for the best flavor.

This soup can be made vegan by substituting margarine or 2 tablespoons of olive oil for the butter.

If desired, you can add cream, but my family likes it the way it is.
