Beef and bean burgers with balsamic onions

Today I want to show you a way to enrich burgers with legumes that I find very interesting to incorporate this ingredient in a different way into our diet. The beneficial properties of legumes are well known and apart from in stews or salads there are other equally delicious ways to eat them.

I am very fond of preparing my own burgers at home. And I like to control what my family eats. If you walk through the supermarket and pick up a tray of beef burgers, you will be surprised by the list of ingredients it contains. To give you an example of the ingredients of some beef burgers that I saw today on the supermarket shelves: beef, water, vegetables, dietary fiber, dextrin, salt, spices, starches, vegetable extract, dextrose, antioxidants, sodium citrate , sodium ascorbate, preservative, coloring... I think that after seeing this list it is worth investing a little time in making homemade hamburgers, right?

Ingredients

• 300g freshly minced beef
• 200g cooked white beans
• 1 egg yolk
• 1 ripe tomato
• 4 slices of cheese
• 2 red onions
• 100ml of Modena vinegar
• Salt
• Pepper
• 4 hamburger buns
• Olive oil

Elaboration

1. Peel the onions. Cut them into thin slices and put them in a bowl with a good pinch of salt and the Modena vinegar . Give it a few stirs and let it rest while you prepare the rest of the recipe.
2. Put the minced meat, the cooked and drained white beans, the egg yolk, a pinch of salt and a pinch of pepper in a bowl. Mix well, helping yourself with a fork while you mash the beans. You don't need to mash them completely, if there are some whole beans left, nothing happens.
3. Shape the burgers with the help of a burger press . With these quantities, you will get 4 beautiful burgers.
4. Grill the burgers on an iron grill with a splash of olive oil .
5. While the burgers are making, toast the bread. The KitchenAid toaster has a function to toast only the inside of the rolls, so it is perfect for these preparations.
6. Assemble the burgers by placing a slice of tomato on the base, the burger on top, a slice of cheese and finally the drained onion.
