My mom and I both liked this! Nice, refreshing flavors combined with easy preparation.. I halved everything because it was just us and that's all the ricotta I had left to use up. I wouldn't quite say it's worthy of a special occasion unless you wanted a quick, easy, and light side for a get together. Seems like it would need some veggies and maybe some meat to hold up as a main dish, but those things are easy enough to add if that's your preference.
