I was trying to apply this rule to our diet, mainly vegetarian with only 2 to 3 meaty night in a week. Last week, we had already enough dinner with meat, so I was thinking to cook something vegetarian on Sunday. I found this recipe online, and would love to make my own version out of it. The result is very good, and it tastes great, especially if you love cheese.
First all of, get the cheese filling, the pesto sauce and the tomato sauce ready. I used a can of plum tomato, cook it with some minced garlic, and season with a touch of salt and pepper, set them aside for later use. Then, work on the pesto sauce, put basil, olive oil, garlic, pinch of salt and pine nuts in the food processors and blend them together. For the cheese filling, put chopped spinach, ricotta cheese, one egg and black pepper in a bowl and mix them together. Preheat the oven to 170C, now get a tray ready. Cut the zucchini in thin slices, remember to get the big zucchini, as big as possible for easy wrapping. Place two pieces of zucchini slices in a cross, and put the cheese filling on top of the cross section, then add some pesto sauce on top, close and wrap up the zucchini. Repeat this process until you finished up with all zucchini slices. Put a layer of tomato sauce in the tray, then lay all zucchini wraps nicely in the tray. Place the tomato sauce on top of each zucchini wrap, as well as some pesto sauce as topping. Lastly, fill the entire tray with grated parmesan cheese, as much as you like. Place the tray in the oven and bake for 20 minutes.
