Spread this earthy flavored pesto on toasted crostini, use it to add depth to tomato soup, or mix it with a bit of mayonnaise and serve with grilled tuna steaks.
Heat the olive oil in a saucepan. Add the garlic, and cook gently for 3 minutes. Do not allow it to brown.
Crush the plum tomatoes slightly, and add them, along with their purée, to the saucepan. Simmer, uncovered, over low heat until very thick, about 1 hour.
Remove the pan from the heat and add the sun-dried tomatoes. Let the mixture rest, 5 minutes
