Hold the 2slices of bread (stacked) in your hands and run warm water over them just until the bread slices are wet, then squeeze the slices in your hands to soften and to remove as much water as possible. Turn the bread into a bowl, breaking up the slices into small pieces using your fingers. Heat the 2teaspoons of olive oil in a small skillet. Add the chopped onion, zucchini, and alittle sea salt. Stir to coat. Cook for about 5 minutes, stirring occasionally, until the zucchini is just tender and has turned golden. Stir in the chipotle chile pepper and alittle black pepper.
Place the ground soy beef in the bowl with the bread, then add the sautéed zucchini and onion mixture, using a spoon to scrape the skillet of any brown bits. Add the minced garlic and jalapeño pepper. Using a potato masher, mash the ingredients to mix well. Taste for seasoning.
Form 6 burger patties using about ½cup of the mixture per burger. Heat a large skillet over medium heat, then spray the skillet with olive oil spray. Add the remaining tablespoon of olive oil, and swirl the pan to coat it with the oil. Arrange the burger patties on the heated oil. Spray the tops with olive oil spray. Cover and cook for about 5-6 minutes until medium brown and firm on the underside, then using a spatula, turn each burger patty, and cook the other side for about 5 minutes until medium brown and firm on the underside. Serve hot.
