1 None onion, finely chopped
7 oz spinach, chopped
2 tsp finely chopped fresh oregano leaves
1 container (15 oz) ricotta cheese
1 1/4 cups grated Parmesan cheese
1 None lemon, peel grated
1/2 tsp ground nutmeg
2 tbsp butter

Preparation

Heat oil in large skillet saucepan on high heat. Saute onion for 3-4 mins, until tender. Add spinach and oregano. Cook for 1 min, until beginning to wilt.

Melt butter in medium saucepan on high heat. Stir in flour and cook for 1 min. Remove from heat. Gradually stir in milk until smooth. Return to heat and cook, stirring constantly, until sauce boils and thickens. Simmer for 3 mins. Remove from heat. Stir in 1/2 cup of the Parmesan cheese and season.
Spoon spinach and ricotta mixture into cannelloni tubes to fill.

Preheat the oven to 350\u00b0F. Top sauce with remaining 1/4 cup Parmesan cheese and mozzarella. Bake for 25-30 mins, until bubbling and golden. Serve with salad.
