Tartines are French open-faced sandwiches that feature thick slices of crusty bread piled high with delicious toppings. This 10-minute recipe utilizes the quick-cooking abilities of a microwave to speed up the process without skimping on flavor. Umami-rich mushrooms join forces with flavorful sun-dried tomatoes, sweet shallots, and creamy cannellini beans to create a hearty and satisfying mixture that’s bound to make your mouth water. The combination of using both dried and fresh sage heightens the earthy flavors of the mushrooms by giving them a bright, herbal kick (if you don’t have fresh sage on hand, usually only dried sage is fine). Spoon everything onto your favorite bread, then use a knife and fork to dig into this tasty toast.

Tip: Mushroom moisture content can vary, so if the mushrooms you use release too much liquid as they cook, microwave the mixture, uncovered, for 30 seconds to 1 minute more to thicken the topping.
