Pierce each potato a few times with a fork. Microwave for 3 minutes (should still be firm). Slice into cubes.
Heat oil in large skillet over medium high heat. Sauté the garlic, onion and bell pepper for 2-3 minutes.
Add potato chunks and season with salt and pepper. Turn every 2-3 minutes.
Slice the smoked sausage into 1/4 inch pieces. Add to the skillet and continue to stir every 2-3 minutes until the potatoes and sausage are browned evenly.
