Do watch out for Quorn products, though. They are made from fungi, but don't mistake that to mean it's made from mushrooms. Apparently many people have bad allergic reactions to Quorn. My husband did (a bad, red rash all over his torso), and we decided not to eat it anymore. I was sorry about that, too, because the chik'n nuggets and a couple of their other products really were quite tasty! Nevertheless, don't go that route.
Also, many of the meat-like substitutes can pose their own problems. Seitan (which I think is awesome) is made from wheat gluten, and therefore not for those with gluten problems or celiac. Other substitutes are made with soy or tofu (well, ok, soy again). Unless the packaging claims "GMO free," then you're feeding genetically modified soy to your family. Soy by itself should be eaten in moderation because of the degree to which an element of it mimics estrogen. It's a useful addition to vegetarian cooking, especially when you're looking for that firm, flavorful, meat-like feel, or perhaps the additional protein, but just be judicious in how often you serve it.
Mushrooms either sliced and baked until they're kind of dried up or sautéd in a little olive oil are great additions to meals that benefit from a 'meaty' taste. The mushrooms actually undergo a chemical change in the cooking that brings out a very similar flavor to meat. We all know about portobellos, but this applies to other mushrooms, even button mushrooms. I've chopped them fine, sautéd them, and added them to spaghetti sauce, soups, chili, and other meals with no one the wiser (if you don't have mushroom lovers in your house) and with a great response to the deeper flavor.
I make a black bean burger that is to die for, and I found the recipe on AllRecipes.com. It's called Home Made Black Bean Burgers. I just leave out the hot sauce, and I like to sauté the onions, garlic, and green pepper a bit before adding it to the mix. AllRecipes.com is a good way to explore some meals that your husband and kids will like without having to commit to a cookbook. That said, one of my favorite cookbooks is called Vegetariana by Nava Atlas (great name!!). I culled through it this summer to try some new recipes, and everything was delicious (and meat eater friendly because it was so flavorful).
One last tip: when I moved our household to only vegetarian meals, I found myself making a lot of stews, soups, beans & rice, and chilis. My kids got totally fed up with the "mushy food." Find ways to serve firm stuff along the way, and a couple of nights serve a meal that resembles a traditional meat & potatoes. For example, black bean burgers, a salad, and sweet potato fries, or fish, colorful roasted vegetables, and pasta. Most of my family loves it when I make falafel. I find the falafel balls in a package at Costco!!! We're dairy free, so I make the sauce from Tofutti Sour Cream with lemon juice, dill, and cucumber. It's delicious!!!
Good luck!
