Cook the green beans until tender about 10-15 minutes.
Drain and let cool slightly. Now grab about 5 beans each and wrap a slice of bacon around them. If necessary, use kitchen twine to secure it or a toothpick. (Rope sticks best)
Now heat a skillet over medium heat with the butter and olive oil. Add the garlic and thyme and sauté briefly. Turn down the heat slightly so the garlic doesn't burn.
Add the haricots verts rolls and fry until the bacon is golden brown. Serve immediately
