Clean the mushrooms, trim off the tough base (with which they were attached to the tree), and slice the rest into larger pieces.
Bring a pot of salted water to a boil, add the mushroom slices, and cook for 20 minutes. Don't cut this short.
In a separate pot, hard boil the eggs for about 10 minutes, then set aside to cool.
Mix the flour (1/2 cup) with garlic powder (4 tsp), salt (2 tsp) and black pepper (1 tsp) in a shallow bowl.
Drain the cooked mushrooms and, while still warm, toss them in the flour mixture. Press the coating onto every side so there are no bare spots.
Heat olive oil in a frying pan over low-medium heat. Fry the coated mushroom slices for 4-5 minutes per side, until golden and crispy on both sides. Rest on a paper towel.
Make the dressing by whisking together olive oil, balsamic vinegar, crushed garlic, and a pinch of salt. Pour half onto the base of your salad plate.
Layer the washed lettuce over the dressing, then arrange the fried mushrooms, halved eggs, tomato slices, corn, and cucumber on top.
Drizzle the remaining dressing over everything and serve with a few slices of good bread.
