Preheat your grill to medium high heat, about 400°F. Clean the grates.
Slice the boule into about 1 inch think slices. Brush both sides with olive oil. Once the grill is up to heat, grill the bread about 5-7 minutes per side. It should be crunchy and have nice grill marks.
While the bread is grilling, mix the ricotta and chives together with a drizzle of olive oil and a large pinch of sea salt. Remove the bread from the grill and cut in half. Slather with the ricotta mixture, an extra sprinkling of salt, some cracked pepper and a drizzle of olive oil.
