Clean the broccoli and the cauliflower. Cut into small pieces and steam in a steamer or pot.
Shred the carrot and place in a bowl in which you want to serve the vegetables. Clean the shrim from the tail if there is one and wash and dry them. Cut the burger buns in half and toast the inside.
Heat up a small pan to medium-high heat. Clean and cut the onion into tiny squares. Once the pan is hot, add the oil and the onions. Reduce to medium heat. Fry them until they start to get a little colour.
Mix the mayonnaise, the ketchup and the seasoning in a bowl big enought to add the shrimp later on. Overseaon it a little as we won’t season the shrimp.
As the shrimp are already cooked we only need to reheat them and give them a good sear. Add them to the pan for 2 minutes. Set aside and let it cool down a little bit.
Now you can put the steamed vegetables to the carrots, as salt and pepper and the 30g of cream cheese and mix it.
Add the shrimp to the sauce and mix it thourougly.
Spread the remaining cream cheese on the bottom of the burger bun, place the arugula evenly on it. Now you can place the srhimp mixture on top of that and close is up with the top part of the bun. Serve on a nice plate together with the vegetables.
