Marinate the tomatoes: Add the tomatoes to a large bowl with the red wine vinegar, olive oil, and 1 teaspoon Kosher salt. Toss to combine and set aside to marinate while you grill the bread.

Grill the bread: Preheat the grill to medium-high heat. Once hot, place the sliced bread on the grates, over direct heat. Grill for 2-4 minutes per side, until crusty and charred as desired. Remove from the grill and set aside. Once cool enough to handle, dice the bread into 1/2-inch cubes.

Assemble the salad: Add the cubed grilled bread to the bowl with the tomatoes. Toss to combine, then let sit for a minute for the grilled bread to soak in the tomato-y dressing. Add in the bell peppers, onion, & feta. Toss to combine.
