D.,
You don't need a wok, a 12 non-stick skillet works better on American stoves. Buy yourself a good, heavy skillet
I highly recommend America's Test Kitchen Family Cookbook. It is one of the few cookbooks that I've received that I've cooked more than one recipe from. The Pan-Seared Chicken in Vermouth Tarragon Sauce tastes like it was made in a 5-star restaurant and is very easy. I also like Chicken Picatta. The Frugal Gourmet Cooks with Wine has the easiest recipe. I've made it so often, I don't even need to look at the recipe. If your kids are skittish about capers, just scrape off the sauce before you serve it to them. My daughter gobbles it up, but I know she'd be suspicious of the capers and onions, so I just don't put the sauce on her piece.
America's Test Kitchen also has several different sauces for pork chops; my favorite is the one with apple cider and dijon mustard in it. We also like Golden Mushroom Pork Chops. This is one of my husband's recipes, so you know it's easy. Brown the pork chops (I like to add a bit of onion for more flavor), then add a can of Campbell's Golden Mushroom soup with half a can of milk. Simmer for about 15 minutes or so. I like to dip french fries in the gravy. I always brine my pork chops before to make them very tender.
If you like tilapia, you'll love flounder. It's readily available at warehouse clubs. You can always panfry it. You might want to try shellfish like shrimp.
I buy sirloin tip steak, then cube it and freeze it. That way, all I have to do is defrost it when I want to make beef stroganoff (lots of leftovers!). My daughter loves Mongolian Beef. The recipee is so easy, I'll include it.
The Marinade
1 pound cubed meat, such as sirloin tip
1 Tablespoon cooking oil
1 Tablespoon corn starch
1 teaspoon sugar
1 teaspoon salt
1 Tablespoon soy sauce.
Pinch of pepper
Mix together marinade. Add beef, mix with marinade, and refrigerate for at least one hour.
To cook: add 1 Tablespoon oil to a large skillet. Add 1 clove garlic, and 1 teaspoon ginger (best before the oil is hot, so it doesn't splatter). When oil is hot, add beef and marinade. Brown beef, when almost done, add 1 Tablespoon soy sauce and one or two green onions, sliced into 2 inch pieces. Serve with rice. Better than anything made at a Chinese restaurant.
My beef stroganoff recipe comes from Betty Crocker. It's a bit too long for this venue.
I've also learned that most vegetables taste better when sauted. I saute asparagus, broccoli and squash in a bit of butter and olive oil. I saute onion with the squash and zuchinni. Yum. No more boiling for me!
Finally, my daughter loves kielbasa. I get Hillshire Farms beef kielbasa, boil it up and serve it with mashed potatoes. The world's easiest dinner, and it is a bit different. I know there are better kielbasa's out there, but Hillshire Farm is easy to come by. By the way, I make the best mashed potatoes. There is nothing healty about them, because I use buttermilk and sour cream and butter (I even add garlic for flavor, but I use a pressure cooker). But I do add about 1/2 cup cauliflower puree, so they are redeemed.
Happy Cooking!
