6 tbsp low-fat mayonnaise
1 tsp lemon juice
1 medium aubergine, sliced into 1cm rounds
2 large Portobello mushrooms
Salt and black pepper
4 ciabattas, cut open and lightly toasted
8 slices of Cheddar, Gouda, or Gruyere
2 large handfuls of rocket or baby spinach
2 tomatoes, sliced
1 Preheat the grill to a medium-high heat.
2 In a small bowl, combine the garlic with the mayonnaise and lemon juice.
3 Use a teaspoon to gently scrape the gills from the mushrooms (they are edible but can turn a dish an unappetising dark grey colour).
4 Coat both sides of the aubergine slices and mushrooms with cooking spray and season. Grill the vegetables for 3-4 minutes, turning once, until tender and browned on both sides. The mushrooms may take 1-2 minutes longer than the aubergines. When cool enough to handle, slice the mushrooms.
5 Spread the garlic mayonnaise on each piece of ciabatta. Place two slices of cheese on the top half of each ciabatta and melt under the grill until bubbling.
6 Layer the aubergines, mushrooms, rocket or spinach and tomato slices onto the bottom halves of the ciabattas and sandwich with the top halves.
