My son still loves veggies, but here are some ways I add more vegetables and nutrients into our food, just because it doesn't change the taste or texture too much. So this may work for you:
--Add pureed squash or pumpkin or carrot to tomato sauce. Sometimes I used jarred sauce, but I find it has too much sugar and salt, so I'll often make my own. You can use boxed or canned tomatoes, mash or puree them, then simmer in a pot with chopped garlic, olive oil, and any spices you like. You can also cook your meatballs/sausage in the sauce to give it more flavor. You can add any veggie you like. Like I said, pureed squash, pumpkin, and carrot are great! (you can get frozen or canned squash and pumpkin. Though frozen has more nutrients).
--add frozen (thawed of course!) squash in place of some cheese for mac and cheese. There are some good recipes online, such as on Food Network.com.
--Make a slaw. I shred apples and shred carrots. Mix together and add lemon juice to prevent browning. Naturally sweet, but healthy too!!!
--Add carrot to baked goods. Muffins, cookies, cakes, etc. You can find some healthier recipes, but you can also substitute healthier items in current recipes (e.g. applesauce instead of oil/butter--though can affect flavor browning a little bit)
--adding tomato to grilled cheese sandwiches before grilling or baking
--add spinach, onions, pepeprs, or anything you like! to calzones. Easy recipe: roll out pizza dough onto an oiled baking sheet (homemade, refrigerated, or from a box. Actually, if you use a mix you could use the water from heating frozen veggies in place of regular water, to help retain nutrients). Cut the dough into however many calzones you want--making 4 triangles or 4 long rectangles is easiest. Mix lowfat/part skim ricotta cheese with an egg and a small amount of mozzarella cheese. Place some of this mixture onto one side of each piece of dough. Top with veggies and then fold the other part of the dough over on top of the filling. crimp the edges and bake at the temperature suggested on the dough package until the dough is golden brown. Make a dipping sauce out of tomato sauce.
--this doesn't"hide" the veggies, but I love this dish. Heat a pan on the stove over medium/medium high heat. Add some olive oil and after it's heated add in some frozen green beans (you can add them in frozen). Heat and allow green breans to brown. After green beans start to heat, add some chopped garlic. After hot and browned, add in some toasted almonds and serve. You can also salt it.
--Another side dish we love: Heat olive oil as in the recipe above. Add a couple crushed red pepper flakes (more or less depending on how spicy you like your food). When oil is warmed, add broccoli--frozen or fresh. While Broccoli browns, add some lemon peel and garlic. When heated through to decided temp and texture, take off heat and squeeze a liberal amount of lemon juice. Mix and serve.
Another tip--see if your daughter can help you make dinner. Her participating may help her be more excited about eating it--even if veggies are involved!
