Place the shallot and garlic in a mixing bowl and add a pinch of salt. Add the vinegar and honey and whisk. Slowly whisk in 1/2 cup olive oil, then add the almonds and mint.
Place the watermelon in a shallow dish. Pour the dressing on top, cover and let marinate 1 hour in the refrigerator.
Heat a large skillet over medium heat and add the remaining 1 tablespoon olive oil. Sear the halloumi 1 minute per side, then remove from the pan; top each with a piece of marinated watermelon.
