Heat the oil in a large sauté pan over medium heat.
Once the oil is hot, add the sausage, season with the red pepper flakes and cook, breaking it up with the back of a wooden spoon, until heated through, 4 to 6 minutes.
Add the tomatoes, onion, peppers and garlic, and season with the sugar, salt and pepper.
Continue to cook, stirring often, until the onions are translucent, and the garlic is fragrant, 2 to 3 minutes.
Next, mix in the tomato paste, broth, soy sauce, and vinegar.
Add the potatoes and carrots, tossing to combine, and increase the heat to high.
Once at a light boil, cover and reduce the heat to medium-low.
Simmer until the potatoes are just barely tender, 20 to 25 minutes, stirring every so often.
Add the peas and olives, mixing to combine.
Simmer uncovered, until the sauce thickens, and potatoes are fully tender, 8 to 10 minutes.
Taste and adjust seasonings if necessary.
Serve immediately with white rice and enjoy!
