Sauce: Add half of the oil (reserving the rest for later), garlic and shallot to a skillet over medium heat. Sautee for about 5 minutes. Stir in tomatoes and cook for another 3-5 minutes. Add in broth and simmer for about 5 minutes until it has reduced. Add capers, cook for 1 more minute and turn off heat.

Fish: Line a baking sheet with foil and preheat your oven's broiler. Prep the fish by rubbing all sides with the remaining oil, and a pinch of salt/pepper. Place the fish on the baking sheet and bake in the broiler on the lowest rack for 6-8 minutes. Check fish every few minutes to make sure it doesn't overcook or get scorched. Tilapia will be done when flesh is opaque and flakes with a fork.

When both elements are done, pour the tomato caper sauce on top of the tilapia and serve.
