Prepare mushrooms by separating and trimming off bottom of stems.
Bring beer to a simmer in a large skillet then add whole sausages and cook for 20 minutes flipping halfway through.
Remove sausages and drain skillet then heat 2 tablespoon olive oil on med-high. Once hot, fry sausages until nicely browned (~3-5 min, flipping halfway). Remove but leave leftover grease in the pan.
Add mushrooms, 1-2 tablespoon olive oil (if necessary) and sprinkle salt and pepper on top. Fry in sausage grease for 3-4 minutes then stir. Repeat until browned (~10 min) then remove from the pan and turn down the heat to medium.
Crack eggs into a mixing bowl with ½ teaspoon salt, ¼ teaspoon pepper, chives & dill and whisk until blended.
Add to the skillet with 1 tablespoon olive oil and stir constantly to cook evenly (~3-5 min).
Remove once the eggs have set then serve with sliced sausages and mushrooms.
