Rinse quinoa and then add to saucepan with broth and water. Follow instructions on package as to how long to cook quinoa. Once done, cover and set aside.
Meanwhile, dice onion and cut off tips of asparagus. Dice the tips and place in a mixing bowl. Dice bell pepper and mince garlic; add to asparagus with chopped parsley, salt, pepper, vinegar, flax, and egg. Chop bread slices and mix in with veggies. Then using your hands, mix well. Shape into patties.
Heat a large skillet over medium and add oil. Once the oil shimmers, add patties. If more oil is needed due to sticking, add 1-2 teaspoons and swirl in pan. Cook each side for 2-3 minutes, heating through and browning both sides.
Dice tomato and use to top patties. Serve quinoa and berries on the side.
