Seedy crisp cracker thins
TOP these with hummus or cheese, which contain tryptophan, an essential amino acid which regulates our mood and has a natural sedative effect.
The healthy carbs in the crackers will help speed up its absorption into your bloodstream.
(Makes 12 crackers)
150g rye flour; 100g wholemeal flour, plus extra for dusting; ½ tsp baking powder; 1tsp fine sea salt; 5 tbsp olive oil; 150ml water; 85g pumpkin seeds and/or sesame seeds.
METHOD: Preheat the oven to 200C/400F/gas 6. Heat some non-stick baking sheets in the preheated oven. Put the flours, baking powder and salt in a large bowl. Make a well in the centre and pour in 4 tbsp of olive oil and the water. Mix to a soft dough. Knead with your hands on a floured surface until smooth.
Roll out as thinly as possible with a rolling pin, brush with remaining olive oil and sprinkle with seeds.
Fold the dough over and roll the seeds into it. Knead lightly and divide into 12 pieces. Roll out each one thinly again.
Remove the hot baking sheets from the oven and arrange the dough thins on them. Bake in batches for ten to 12 minutes.
Cool on a wire rack and store in an airtight container for up to five days.
1 x 1.5kg oven-ready chicken; 1 large onion, diced; 3 carrots, diced; 2 leeks, trimmed and shredded; 4 celery sticks, diced; 2 garlic cloves, crushed; 2 bay leaves; 3 fresh thyme sprigs; 1.8 litres water; 225g vermicelli noodles; Juice of ½ lemon (optional); 1 large bunch flat-leaf parsley, finely chopped; sea salt and black pepper.
METHOD: Put chicken in a large saucepan. Add the veg, garlic, bay leaves and thyme. Pour in water, season and bring to the boil on high heat.
Reduce to a simmer and partially cover with a lid. Cook gently for two hours, until veg is tender and the meat falls off the bone.
Remove chicken from pan and set aside until cool enough to handle.
Discard skin, cut meat into pieces and return it to soup with the noodles and most of the parsley.
Simmer until the noodles are cooked. Remove bay leaves, stir in lemon juice and serve with remaining parsley.
Prawn and spinach linguine
PRAWNS contain the calming amino acid tryptophan, while spinach provides a good source of magnesium, which relaxes the muscles and helps steadies the heart’s rhythm.

Turn and cook the other side. Stir in the remaining parsley and spinach. Season to taste.
Add the cooked linguine and gently toss everything together.
