I'm also a fan because they are a hands-on food. I'm sure you can make meatballs without your hands, but it would be a horrific bother. When I was a kid, helping my mom make meatballs was one of my favorite things. I got to play with the food!
First, you're going to need to dry out your bread. If you have stale bread sitting around, you're in luck and can probably skip this step. If you don't, turn your oven on to the lowest temperature setting, and put the bread in for a few minutes. In the meantime, you can get all your other ingredients together. Just combine them in a bowl. When the bread is dried out (or at least mostly so) crumble/tear it into the bowl with the other ingredients. You want the pieces to be as small as possible, because you don't want a hunk of soggy bread in the middle of your meatball, but don't worry too much, because you're going to further mash it in a bit.
Yet another nice feature of meatballs is that they are best made with the cheapest, fattiest hamburger you can find. Otherwise, they have a tendency to be dry. Hooray for cheap meat! Want to stretch your food budget even further? How about incorporating another protein, such as lentils? That's what I did here.
1 piece bread
1/4 lb hamburger
1/3 C cooked lentils, cooled
1 egg
2 tsp Worcestershire sauce
1 Tbsp Italian seasoning
2 Tbsp chopped onion
1 Tbsp (a hearty, 4-finger pinch) grated cheese
Salt and Pepper to taste
Before you get started, preheat your oven to 350˚F.
Once all your ingredients are in a bowl, be sure you have clean hands (I'm everyone washes their hands before cooking anyway, but just to make extra-sure here.), reach in there, and sort of squeeze everything together. Do this a few times, until everything is well-combined and homogenized. Form into spheres and arrange on/in a baking pan. Bake until the center of the meatballs are 170˚F (USDA recommendation). Pick the largest meatball to be your tester, so you only have to poke holes in one of them.
As you can see in the photo (left), they look a little funky after cooking-- the fat liquifies and solidifies, and it's not a pleasant thing to see. Don't worry. As you remove the meatballs from the pan, the nasty stuff wipes right off, and you'll be left with a presentable meatball. That's the disadvantage to baking meatballs on their own.
I thought these turned out quite nicely. I ate them over spaghetti squash (as you can see in the photo), and with pasta. My fiancé ate them plain. He said they were good, but he also asked why I always put weird things (like lentils) in my food. So, taste-wise, I think they were a success. However, the lentils remain obviously lentils, so they may not be the thing to serve a picky eater.
