No, you cannot sell salsas, tomato sauces, spaghetti sauces, or focaccia bread with roasted vegetables.
Cooked vegetables, whether fresh or canned, usually are made from a combination of low acid and acidified food, and are considered a potentially hazardous food. Cooked vegetables must be kept either hot (above 135°F) or cold (below 41°F). They cannot be stored safely at room temperature, which makes them a prohibited product for cottage food operators.
