In a large skillet over medium-high heat, warm the oil and add the garlic, cooking until the oil around the garlic starts to bubble and some (but not all) of the garlic pieces are lightly toasted and brown, 1 1/2 to 2 minutes.☞ TESTER TIP: Choose a skillet that has lots of surface area. You’ll need it as the escarole takes up quite a lot of space prior to being wilted.
