This dish is so fresh and full of flavor!!
In a small saucepan, bring the balsamic vinegar to a boil and then reduce
heat to a simmer and let cook about ten minutes, until thickened and syrup-y.
In a large saucepan, melt the butter and then add the chopped onion and let
cook until softened, about five minutes.
Add the rice and cook, stirring occasionally, for about two minutes.
Add the broth half a cup at a time, stirring well between each addition and waiting to add the next serving of broth until the previous one is completely absorbed. This should take about 35-40 minutes total. Add the salt about half way through.
When all the broth is absorbed and the rice is creamy and tender, stir in
half-and-half and pesto or basil.
Remove from heat and add tomatoes and mozzarella, stirring well to combine.
Salt and pepper to taste, and serve, drizzling the balsamic syrup over each serving.
