1 recipe Crispy Corn Bread or 3 cups of 1-inch cornbread cubes
1 1/2 pounds ripe tomatoes (4 to 6 medium)
6 cups roughly torn sturdy fresh lettuce, such as Bibb, butter or Boston
2 cups bitter greens, such as arugula or dandelion greens
1 large Vidalia onion, trimmed, peeled, sliced crosswise as thinly as possible and separated into rings
1 recipe Buttermilk-Lime Dressing
Preheat oven to 250°. Scatter the corn bread in a single layer on a half-sheet pan and bake until the pieces are lightly toasted, about 7 minutes.
If you wish to peel the tomatoes: Cut an X in bottom of each tomato and blanch in a large pot of boiling water 10 seconds. Immediately transfer with a slotted spoon to an ice bath to cool. Peel tomatoes and chop them. (The Lee Bros. also suggest seeding the tomatoes, but I drew the line there.) Otherwise, just chop the tomatoes with the skin on.
Place lettuce, greens, 3 cups of toasted corn bread, onion and tomatoes to a large bowl and toss to combine. Drizzle with buttermilk dressing, season with salt and pepper, and toss again. Serve immediately.
Do ahead:
If you’re making this for a picnic or pot-luck — and oh, you should — I suggest keeping the croutons in one container, the dressing in another and the salad mixture in a third; this is best freshly assembled, or in the 30 minutes after.
