Chicken Tetrazzini (creamy chicken mushroom pasta bake)

Melt 2 tbsp butter in a large pot over high heat. Add chicken, sprinkle with pinch of salt and pepper. Cook 1 1/2 minutes until golden.

Turn chicken, sprinkle with salt and pepper. Cook 1 minute until golden then remove onto plate - doesn't need to be fully cooked (will cook more in oven).

Rest 5 minutes, then chop into small pieces, or shred.
