300 Calories


  • 34 cup roasted, unsalted nuts

  • 34 cup whole wheat flour

  • 3 tsp of zero-calorie Truvía® Natural Sweetener Spoonable***

  • 12 tsp kosher salt

  • 6 Tbsp cold unsalted butter, cut into 12-inch cubes

  • 2 egg whites

  • 2 Spanish or Vidalia onions, peeled and cut into wedges

  • 1 red onion, peeled and cut into wedges

  • 2 Tbsp balsamic vinegar

  • 1 tsp olive oil

  • 1 cup fat-free ricotta

  • 2 eggs, beaten

  • 14 tsp kosher salt

  • 14 tsp black pepper

  • 1 Tbsp fresh thyme


  1. Preheat oven to 400° F.

  2. In a food processor, pulse nuts until coarsely chopped. Add flour, Truvía® Natural Sweetener and salt and pulse to combine. Add butter and pulse until the mixture resembles a coarse meal. Add egg whites and pulse just until dough comes together and forms a ball. Add a tablespoon of ice water if mixture needs more liquid to come together. Press dough with wet hands into a 9-inch tart pan with removable bottom into an even layer and up the sides. Refrigerate for 1 hour.

  3. On a sheet pan, combine onions, balsamic, oil and 134 tsp Truvía® Natural Sweetener (or 2 packets) and toss to coat. Roast for 20 minutes, turning onions over halfway.

  4. In a small bowl combine ricotta, egg, salt, pepper and 34 tsp Truvía® Natural Sweetener (or 1 packet) and stir. Evenly spread filling on bottom of the tart shell. Carefully arrange roasted onions in a rosette pattern, saving the smaller pieces for the middle. Sprinkle with thyme and bake for 20–25 minutes or until crust is golden and filling is set.

  5. Let cool 10 minutes before cutting into wedges.
