Arrange the cherry tomatoes onto the baking tray. Season lightly with olive oil, salt, and pepper. Bake for about 10-15 minutes.
Meanwhile, melt butter in a stovetop pan over medium heat.
Get the pan off the stovetop. Add flour and mix with a steel whisk.
Next, add the mustard, beer, and grated Cheddar cheese.
Return the pan to the heat and stir over low heat.
When the sauce turns creamy, remove the stovetop pan from the heat.
Add salt, paprika, and black pepper to the sauce and mix with the steel whisk.
Drop an egg yolk in the sauce and mix again.
Remove roasted tomatoes from the baking tray.
Arrange the slices of bread directly on leftover tomato juice.
Toast the bread slices on one side in the oven.
Remove the baking tray, turn the toasted bread slices over, and spread the sauce over them.
Return the bread to the oven and bake until golden.
Get the baking tray out of the oven and serve with roasted cherry tomatoes. Sprinkle fresh thyme and oregano on top. Serve with some greens if possible.
