I have been eating vegetarian for the past week and one important piece of information that I've discovered is that when you don't eat meat, poultry or fish, you have to be sure to get a good source of vitamin B12. The best vegetarian source of B12 is nutritional yeast. I used it at the table to sprinkle 2 tsp over my own lasagna instead of parmesan cheese as it has a kind of savoury, cheesy taste to it. This is not the same as brewer's yeast. It is a yeast that is grown on molasses and three tbsp contains more than your daily requirement of vitamin B12. You shouldn't eat more than 3 tbsp of it a day, because that can raise the uric acid levels in your blood, which is not good for your kidneys and can cause gallstones and gout.
I have not given up my eggs or my probiotic yoghurt. While I love the cheese in this lasagna, believe it or not, I am not a big cheese eater! I think it's all the delicious sauce that goes with it and makes the perfect combination. It was a big hit here yesterday!
Sauce:
2 tbsp olive oil
1 small onion, finely chopped
2 garlic cloves, finely chopped
2 cans (28 oz each) diced tomatoes & their juice
4 tbsp tomato paste
1/2 tsp salt (or less)
1/2 tsp coarsely ground black pepper
2 tbsp chopped fresh basil leaves (or 1 tbsp dried)
1 tsp dried red chili peppers
1 jalapeno pepper, chopped (optional)
Cheese filling:
1 large egg
1/4 tsp coarsely ground black pepper
1 container (16 oz) light ricotta cheese (5% milk fat)
½ cup grated mozzarella cheese
1 1/4 cup freshly grated parmesan cheese (set aside ¼ cup to sprinkle over lasagna later)
2 cups chopped baby spinach (chop before measuring)
1 tsp garlic powder
1 package fresh, no boil, lasagna noodles (6 noodles about 6 inches in width)
Directions:
- Prepare sauce: Heat large heavy bottomed saucepan over medium high heat. Add olive oil, onion & garlic (& jalapeno, if using) and cook about 2 minutes.
2. Stir in tomatoes with their juice, tomato paste, red chili peppers and salt & ground pepper; heat to boiling. Reduce heat to low and cook uncovered, stirring occasionally, about 30 minutes. Stir in basil.
3. Meanwhile, prepare filling. In medium bowl, mix egg, pepper, ricotta, mozzarella, spinach and 1 cup of the parmesan until blended.
4. Preheat oven to 375F. In 13 x 9 inch glass baking dish, evenly spread 2 cups of sauce. Arrange one noodle over sauce ( noodles will expand while cooking). Top with 1 cup cheese filling, spreading across noodle. Place another lasagna noodle over the cheese and top that with 2 more cups of sauce. Continue to layer in this way until you have used 4 of the lasagna noodles. Top with 2 cups of sauce. (If making a day ahead, cover and refrigerate at this point).
5. Cover lasagna with foil and bake until heated through and bubbling, about 50-60 minutes (15 minutes longer if it was refrigerated). Remove foil. Sprinkle with remaining 1/4 cup parmesan and cook another 10 minutes. Let stand 10 minutes, uncovered, before cutting, for easier serving. Have some extra grated parmesan cheese on the table to sprinkle on top.
