I have a 7.3 lb turkey breast (bone in) can you recommend oven temp and estimated time?

Hi Mary, 325F at roughly 20 minutes per pound is a good basic rule of thumb if you don't have a recipe you're following, but the internal temperature is the most important indicator of whether the meat is cooked through. It should be 165F in the thickest part once it rests. Once it hits 160F you should be good to take it out, since the temperature will keep climbing as it rests. Here's more details on timing if you like to look at other options: https://food52.com/blog/18372-the-essential-numbers-a-guide-to-times-and-temps-for-cooking-your-bird
