If you don't make the fries the total time (Mixed Herb Greek Yogurt Dip + Salmon Burgers) is 35 minutes total.
You might be tempted to use a food processor to chop the salmon up really small but don't. This dries it out and makes the burgers more dense.
Make the Mixed Herb and Greek Yogurt Dip first (or better yet, make it on a completely different day to be nice to yourself)
If you follow this order, it will help insure everything finishes up at the same time: (1) Cut the potatoes into fries and soak them in water for 30 minutes. Put the salmon in the freezer for 20 minutes. (2) Prep all the ingredients while the fries soak and the salmon firms up. (3) Once the fries are finished soaking and are drying on paper towel lined cooling racks, finely chop the salmon. (4) Put the fries in the oven. While they're cooking make the salmon burgers and prepare the condiment ingredients. (5) Begin cooking the salmon burgers when the fries are on their last 5 minutes and broil the buns as soon as the fries are out of the oven.
