Preheat the oven to 425 degrees
Put the four potatoes in a large saucepan and fill water to just over the potatoes. Put over high heat on stove.
Line a large baking sheet with aluminum foil, set aside.
Add all of the ingredients of the glaze into a small bowl or glass measuring cup. You can either finely mince the garlic or use a garlic press. Stir all of the ingredients together and set aside.
Rinse the frozen broccoli under cool water to help defrost it a bit. Let it drain in the colander and then transfer to paper towel lined plate to soak up the water.
Unwrap the salmon from its packaging. If the potatoes are not finished boiling, set the fish in the fridge and get it out right before its time to go in the oven.
Once the potatoes are done boiling, transfer them to a paper towel line plate so they can drain a bit.
Once potatoes have drained a bit, transfer them to foil lined pan. I use the bottom of a glass to smash the potatoes down just until the skin breaks open. Brush the potatoes with 1 tbsp of olive oil and sprinkle the cumin over them.
Arrange items on the pan so they all fit nicely. Brush the salmon with the glaze. If there is extra, you can brush it over the potatoes and broccoli. I put some on half the broccoli and half the potatoes. Brush the broccoli with 1 tbsp of olive oil and sprinkle some salt and pepper over them, to taste.
Cook for 15 minutes, or until the salmon flakes away easily with a fork. At 425 degrees, it takes 4-6 minutes per half an inch of salmon to cook through. Salmon should reach 145 degrees internally, measured through the thickest part.
