4. Blanch the tomatoes for a few seconds; peel and cut into quarters or eighths.
5. Slice the garlic into thin slices.
6. Heat a little olive oil in a Dutch oven or cocotte. When it is hot, add the garlic unti the oil is flavored, then add the tomatoes and onions. You don't need to stir.
7. Once the vegetables have sweated, reduce the heat and add half the teriyaki base and the meat. Sprinkle with basil at the end of the cooking.
