In a large skillet sauté the onion in olive oil for 2 minutes. Stir in the garlic, then the orzo.
Let the orzo toast for a few minutes, then add in the white wine.
Pour in the chicken broth, and petite diced tomatoes. Add salt and pepper, then bring to a boil.
Reduced heat to low, cover and let simmer for 12 minutes, stirring occasionally, until the orzo is cooked through and the sauce has thickened.
Stir in the chickpeas and let them cook for a minute or two to heat through.
Top with grated Parmesan cheese and fresh chopped basil, if desired.
