As promised, here is my recipe for Ravioli Roll-ups:
1 egg, beaten
1 container ricotta cheese (15 oz) - full-fat or part-skim work fine
1 bag of Kraft 5-cheese Italian Blend (8 oz., already-shredded)
Green onions, chopped - I use anywhere from 2-4 green onions, depending on size. Use 3 to start and adjust next time
1 tablespoon Italian seasoning - I use McCormicks
2 jars spaghetti sauce - I use Prego Heart-Smart Roasted Red Pepper & Garlic, use whatever sauce you like best
16-18 lasagna noodles, parboiled (1 package worth)
Shredded cheese for topping - Parmesan, Mozz, or Provolone all work well
---------------
Heat oven to 375°.
Mix first 5 ingredients together by hand and mix well. Store in fridge.
Cook lasagna noodle for ~75-80% of total cooking time (for Barilla, which calls for 8 minutes, I boiled for ~6.5 minutes), drain and lay noodles out flat on several cutting boards or a clean countertop.
Spread some of the cheese filling on to each noodle (using your fingers works better than a spoon); eyeball it and make sure each noodle gets a roughly equal amount. Spread the filling out on all noodles before rolling.
Spread ~1 cup of spaghetti sauce into the bottom of a 13x9 baking dish. Roll each lasanga noodle, and lay seam-side down.
Once the pan is filled (I can fit 18 rolled lasagan noodles in a 13x9 pan with no fuss), spread remaining spaghetti sauce over noodles. Make sure noodles are covered all over.
Cover with shredded Parm/Mozz/Prov (1/4 to 1/3 cup total works well), and cover pan with aluminum foil. Bake 40 minutes; remove foil, and bake 10 more minutes uncovered.
Once done, let sit for ~10 minutes (covered w/ foil) before eating.
Note: this dish takes a long time to cool down (if left in the original baking dish) before storing in the fridge; if possible, separate into individual portions for faster cooling before stowing in the fridge.
