Some people think bacon makes everything taste better - bacon in dessert is just one example - but I am going to make a case for breadcrumbs. If your kid isn't into vegetables or won't try something new, breadcrumbs might convince him otherwise.
I especially like Panko, Japanese style breadcrumbs, because of the crispy texture. Panko absorbs less oil than traditional breadcrumbs so you may find your dishes less greasy. Coat veggies such as sweet potatoes, sweet onions, or green beans and fry them in a heavy pan. Absorb the extra oil on paper towels and serve them hot - or warm for the little ones. It's a deliciously different way to serve the same old vegetables. Fish may be the best candidate for Panko breadcrumbs. Kellan will pretty much reject any fish, but he will try it if it's breaded and crisp. I even season the breadcrumbs with salt, pepper, and chopped parsley to add flavor. You don't even have to fry foods to use breadcrumbs. Dishes like baked macaroni and cheese or steamed asparagus can be healthy and low fat.
We don't do many bread crumbs as that would be too much for my daughter who would pull it apart first to investigate what was hiding. I know curiosity is a good thing, but I don't always feel that way at the dinner table.
We have found that presentation is everything (we loved the pumpkin soup idea!) We have broccoli trees that stand up in rice for a forest, we sprinkle on Parmesan for snow and they love that. We will sometimes add cauliflower for the winter trees. We make rainbows out of peppers that are always a big hit. Carrots and cucumbers are always good for making faces or other shapes. I find they do play with them a bit, but eat them too. I will sometimes make the rainbows or veggies faces/shapes for snacks as this seems to take away any idea of it being a healthy meal.
They eat lots of veggies this way and even sometimes make up their own. Our biggest issue at home is meat, we've tried breaded, plain, in things, etc. But my oldest just will not eat it. I'm hoping it is a stage.
