Step 1

Make cashew cheese sauce.

Step 2

Preheat grill (broiler). Place cauliflower, oil, garam masala and chilli in a medium bowl; toss to combine. Season. Spread cauliflower on an oven tray; place under grill for 15 minutes or until soft and golden, stirring occasionally.

Step 3

Meanwhile, cook pasta in a large saucepan of boiling salted water until just tender; drain.

Step 4

Combine cauliflower, pasta, half the parsley and half the cashew cheese sauce in a large bowl. Spoon mixture into an 18cm x 23cm (7¼in x 9¼in) ovenproof dish. Spoon over remaining sauce. Grill for 4 minutes or until golden. Serve topped with remaining parsley.

Step 5

Place cashews in a medium bowl; cover with filtered water. Stand, covered, for 4 hours or overnight; drain cashews. Rinse under cold water; drain well. Heat oil in a medium frying pan over medium heat; cook onion and celery, stirring, for 8 minutes or until soft. Add to a high-powered blender with cashews and remaining ingredients; blend until smooth. Season to taste.
