Ham and Dijon Croissant Sandwiches

"Melt-in-your-mouth baked croissant sandwiches of thinly sliced ham, Swiss cheese, and a delicious buttery Dijon and poppy-seed sauce! Perfect for luncheons or entertaining, or packed into picnic lunches; great served warm, or at room temperature. Use as much ham and cheese as you like! Sandwiches are easily made up in advance and individually wrapped in foil, then refrigerated or frozen (use a freezer bag) for later use. Defrost overnight in the fridge, then bake as directed. Or, if frozen, bake at 300 F for about 1/2 hour until warm. If using mini-rolls, you may place them in a buttered baking dish and bake for the specified amount of time (no need to individually wrap)--I've also microwaved them. Enjoy!"

    These are terrific. I just made some for lunch and my kids devoured them, when coming home from school today. Thank you for such a good recipe.

    My mother in law makes this, but just uses small kaiser rolls. This is a great recipe, easy to make ahead and great to have on hand. Kids and adults love these!

    I made these last night, and they are exactly the cheesy, gooey deliciousness I was looking for! I made them with several extra thin slices of ham (instead of just one like the recipe calls for) and added a slice of American cheese along with the swiss, because that's the way I remember Ham & Cheese from my childhood. So, so good, and very easy to make!


<p>Married to my sweetheart for almost forty years and we have two wonderful children who are grown and have flown the coop. Also, we have been blessed with a wonderful son-in-law and beautiful daughter-in-law, plus FIVE grandchildren: two beautiful granddaughters ages five and eight, and three sweet adorable little grandsons ages 2 months, 2 years and 3 years. My husband and I share a combination of English, Irish, Scottish, Welsh, Dutch, Swiss, Polish, Austrian, German and French heritage, and our son-in-law and daughter-in-law are both Hispanic. We've traveled extensively to many countries abroad (we lived in Germany), and have traveled and lived in several states here in the U.S.A. Many of the recipes I post here are influenced by our combined heritage or from our travels, or they are old family favorites that I want to share with you. I hope you enjoy! Have been to culinary school with many years of cooking (mostly for my family) under my belt, so know my way around a kitchen. And I'm very lucky to have the best sous chef in the world, dddddh! One of my favorite chefs of all time is Jacques Pepin! I have several of his cookbooks, and enjoy watching his television cooking show Fast Food My Way. Another top favorite is Julia Child (of course!). A few other chefs I read/enjoy watching on t.v. are: Giada At Home, Ina Garten's The Barefoot Contessa, Nigella Lawson's Nigella Bites, and Patti's Mexican Kitchen, and many more. On my bucket list is dining at Thomas Keller's establishment The French Laundry in Napa Valley, California... as well as Alice Waters' Chez Panisse in Berkeley, and the James Beard award winning Tartine Bakery and Cafe in San Francisco. One day!! &nbsp; Hobbies/Interests: Decorating with fresh flowers and herbs from the garden is my passion, and brings me deep joy! It's really hard to beat!! I love connecting with others who enjoy the same. Gardening, decorating, sewing, music, dancing, film, and reading are also up there. Spending quality time with my grandchildren, family, and friends (and cooking holiday meals!). Currently, a newfound passion has been so richly rewarding for me: genealogical research. I heart ancestry dot com. And last but certainly not least, I absolutely LOVE cats--we have two half-Siamese fur babies (cats) that allow us to live here!!&nbsp; &nbsp; A Note of Thanks~ I try to personally thank everyone who kindly makes and reviews my recipes, but sometimes I am busy, late, or may forget. Please know that I am always humbled that you would try one of my recipes, and I enjoy reading the reviews and seeing all the pretty photographs. Thanks so much!&nbsp;</p>
