Entertaining can be easy -- and good for you. These bites with lycopene-rich tomatoes and heart-healthy avocados are a virtuous and delectable cocktail party offering.
Preheat oven to 350 degrees. Slice baguette diagonally into sixteen 1/2-inch-thick slices; brush both sides with a total of olive oil. Bake on a baking sheet until golden, about 8 minutes.
Halve avocado lengthwise and remove pit; scoop flesh into a small bowl. Mash with lemon juice; season with coarse salt and ground pepper. Spread on toasted bread; top with grape tomatoes.
