In a microwave-safe bowl, cook cut green beans and diced potato in 1 cup of the broth, covered, for about 5 minutes, or until beans and potatoes are soft, but not mushy (remember, they’ll continue to cook with the bulgur). Remove the vegetables from the broth using a slotted spoon. Set aside. SAVE the cooking broth!
Combine the remaining cooking broth with enough chicken broth to equal two cups; pour into a large saucepan.
Bring the 2 cups of broth to a boil. Stir tomato paste into the hot broth and blend.
Add the green beans, potatoes, bulgur and seasonings to the broth. Bring to a boil; reduce heat, cover and simmer 15 to 20 minutes or until liquid is absorbed. Remove pot from heat. Allow bulgur to rest about 5 minutes after cooking.
While the bulgur is cooking, heat 1 to 2 Tbsp. olive oil in a skillet. Sautė onions until they are caramelized (a deep golden brown) – about 7 to 8 minutes. Set aside.
Fluff bulgur with a fork; place in a serving bowl. Top with caramelized onions before serving – or gently stir onions into the bulgur, if you prefer.
