I'd like to have at least a least one side and a salad. Plus a vehicle for the chicken salad?
Do I understand correctly that you want to serve
▪ Moroccan chicken salad
▪ Side salad (green veg or lettuce)
▪ Second side dish
▪ Vehicle for the chicken salad (bread?)
If you make the sweet potatoes as the second side dish, you'll gave a nicely balanced meal...protein, green and orange veg, carb.
Serve potatoes any temp you prefer, but warm or hot will give more flavor.
I also don't see a problem. That temperature difference can enhance a meal.
I don't think it's weird at all. I like serving some things at room temp and some things hot.
