Heat half a tablespoon of olive oil in a non-stick skillet over a low/medium heat. Thinly slice the onion. Add the onion to the skillet and pan-fry gently for a few minutes until tender, lightly golden, and starting to crisp. Remove from the skillet and set aside.
Step 2
Wipe any excess oil from the skillet and turn the heat up to medium/high. Slice the halloumi lengthwise into two even-sized rectangles. Place the halloumi pieces in the hot, dry skillet. Cook for 2 minutes until browned, then turn and cook on the second side for a further 2-3 minutes until golden all over.
Step 3
Add the remaining olive oil, tahini, garlic powder, salt and lemon juice to a small bowl. Mix well until smooth and combined. Taste and adjust seasonings as required.
Step 4
Arrange the lettuce leaves on serving plates. Thinly slice the tomato and avocado. Arrange the tomato and avocado in the lettuce cups.
Step 5
Place the fried halloumi on top of the avocado. Scatter over the fried onions. Drizzle over the tahini dressing and serve immediately with your preferred Keto sides.
