Cook pasta according to package directions. Immediately drain. Return pasta to pan; keep warm.
Meanwhile, place artichoke hearts in a colander under cold running water to separate. In a large skillet cook and stir artichokes, sweet pepper, onion, and garlic in hot oil over medium-high heat for about 5 minutes or until vegetables are tender.
Stir in tomato and basil; cook and stir about 2 minutes more or until heated through. Add artichoke mixture to pasta. Toss gently to mix. Sprinkle each serving with Parmesan cheese. Makes 4 to 6 side-dish servings.
