I based the first on pasta with pesto, a bright, herby Italian crowd-pleaser with warm weather associations: Even just thinking about pesto makes the sky outside seem a little more blue. To add protein and heft, I stirred in some ground turkey, and a handful of baby spinach for a colorful pop. If you happen to have homemade pesto squirreled away in the freezer, this is the perfect time to use it. But store-bought pesto works just as well, its garlic and basil pungency infusing the broth like a welcome summer breeze.
