In a microwavable baking dish, arrange tilapia fillets in a single layer. Dot with pieces of butter, and minced garlic. Sprinkle over fresh tarragon. Cover with waxed paper and microwave on high for 2 minutes.
Turn fillets over, re-cover, and continue to microwave on high for a further 2 minutes. Remove immediately and serve.

Season steak on all sides with some salt and pepper.
Heat half of the oil in a skillet over medium-high heat. Add steak and cook to desired doneness, 4-8 minutes per side. Remove steak and set aside to rest.
Lower heat to medium and add in remaining oil and the shallots to the pan. Stir and cook for about 2 minutes until lightly softened. Stir in vegetable broth and cook for about 2-4 minutes until the broth is reduced by about half. Turn off the heat and stir in butter until fully melted.
