Heat oil in a large saucepan over medium-high heat. Add pepper and onion. Cook and stir until vegetables are crisp-tender. Stir in small sweet potato cubes, broth and home-spice blend or jerk seasoning. Bring to a boil. Reduce heat; simmer until potato is tender, about 15 minutes.

Meanwhile, cook pierogies according to package instructions (I prefer to lay the frozen pierogies in an inch of boiling water in a large skillet, overlapping them slightly; don't bother sauteeing them in butter afterwards.)

Drain the pierogies and divide among warm dinner plates; keep warm. Add black beans to the vegetable mixture and heat through. With a potato masher or fork, mash a small portion of the vegetable mixture against the saucepan to slightly thicken sauce. Spoon over the pierogies.

Note: Use vegetable broth in place of chicken broth for a vegetarian entree. If you can't find jerk seasoning at the supermarket, blend garlic salt, ground allspice and red pepper in desired proportions.
