Spinach with Almonds

• 1 kg (2 lb) spinach
• 1 onion, coarsely chopped

Wash the spinach, remove hard stems and shred if the leaves are large. Sauté the onion in oil until soft, then add the spinach and cook gently, stirring, until it crumples. Add salt and pepper and the tomatoes and cook until they have softened only slightly. Toast the almonds and stir them in just before serving.
