Can one eat pareve food baked in dairy utensils (tray) together with pareve food baked in meat utensils?
Answer:
Yes, there is no problem in this.
Pareve food baked in dairy utensils remains pareve.
Although according to Ashkenaz custom (Yoreh De'ah 95:2) if the utensils were ben-yomo it is not permitted (on a lechatchilah level) to eat the food with actual meat. However, there is no problem with eating it with pareve food baked in meat utensils.
Best wishes.
