Sometimes "all thriller, no filler"  shouldn't be your mantra in life, and that's if and only if you're talking about ravioli. You can't go wrong with pasta stuffed with delicious cheese and other fillings, whether it's the traditional ricotta and meat or a carb-on-carb explosion like pierogi.

In celebration of the return of My Grandmother's Ravioli on July 29 at 8pm ET, we're going 'round the world with  six versions of "ravioli," from the Italian classic to Japanese gyoza to apple dumplings for dessert. Get ready for your taste buds to jet to many flavorful destinations — all without leaving your kitchen.

The ultimate Italian comfort food is pillowy cheese ravioli filled with creamy ricotta and topped with homemade marinara sauce. You can't beat this classic.

Sometimes the only solution to your problems is carbs on carbs. Nadia G's pierogi are loaded with potatoes, garlic and cheddar and topped with fried onions — and could brighten any bad day.

The trick to perfect Japanese dumplings is searing, then steaming. The extra work of making these instead of calling your local takeout joint is well worth it — especially after you smother them in ginger dipping sauce.

After making an easy dough from flour and eggs, all you need to do is put together onions, garlic and chicken. Five ingredients make for a super-delicious and easy Siberian dish that tastes as great as a bowl of pasta and meat.

Play fast and loose with the idea of a "dumpling" with this flaky apple dessert. We'd love to see Mo Rocca cook up some of these decadent treats on My Grandmother's Ravioli.

If it's dough with a filling, it counts as a ravioli, right? These Indian-food staples are usually filled with potatoes, but our version adds cauliflower into the mix for a slightly healthier version that doesn't skimp on flavor.
