Inlaws coming for supper! But I'm new to cooking☹

So my inlaws are coming for supper and I wanna make meatballs in a crockpot. I've looked at some recipes online but at each recipe I've looked at say something different about the cook time. (I know just follow the recipe. But I want them to be good!)

1 recipe said to put the meatballs in the crockpot raw with a sauce and cook them.

Another said to broil the meatballs for a few minutes, before cooking them in the crock pot, so they dont fall apart. Most recipes said to cook on low for 4 to 6 hours.

What do u think I should do? I dont want them to fall apart but I want to do it the faster way. Which would be to put them in the crockpot raw.

Also what would you do for sides? I'm thinking a salad and mashed potatoes.🤷‍♀️
