Step 1

Preheat your oven to 400 degrees.

Step 2

Heat a large saute pan over medium heat. Add 1/4 c. of the butter and cook until it foams, turns clear, and is brown in color. Add half of the bread pieces and toss with the browned butter. Transfer to a baking sheet. Repeat with remaining butter and bread pieces.

Step 3

Arrange the bread on the baking sheet in a single layer, then bake 10 minutes, turning once halfway through. Let cool.

Step 4

In a small bowl, whisk together the dry mustard, vinegar, olive oil, pepper, garlic, and dried oregano.

Step 5

Combine the tomatoes and mozzarella in a large bowl. Pour the vinaigrette over the top and toss to coat. Once the bread has cooled, fold the croutons into the salad mixture. Let sit 15 minutes so the croutons can absorb some of the dressing. Fold in the basil leaves immediately before serving. Enjoy!
