Rinse and dry your leafy greens (if necessary) and grape tomatoes. Slice your tomatoes in half lengthwise and finely slice your red onion. You can also chop your basil now to use in your homemade vinaigrette.
Add the arugula, tomatoes, and red onion to a large salad bowl or large serving platter and toss to combine. Place the burrata on top and set aside until ready to dress and serve.
Basil Balsamic Vinaigrette
Add the basil, balsamic vinegar, olive oil, honey (or maple syrup), salt, and pepper to a jar fit with a lid. Close the lid tight and shake vigorously to emulsify.
Notes
Burrata is best served at room temperature! Consider taking it out of the refrigerator about 20 minutes before assembling this salad.
