To begin making the High Protein Paneer Tikka Sub Sandwich with Tandoori Mayo, first prep all the ingredients and keep it by the side of the cooking counter. Prepping ingredients helps speed up the cooking process.

To begin making the paneer tikkas in Tandoori Mayo, in a large mixing bowl, combine all the ingredients mentioned under the "Tandoori Mayo Paneer Tikka". Toss to coat the paneer pieces well. Check the salt and seasonings and adjust accordingly. Cover and set aside for 10 to 15 minutes to marinate.

Heat a teaspoon of oil in a pan. Add the Tandoori Mayo Paneer Tikka mixture into the pan. With the heat on low, toss the Paneer Tikkas until it gets well roasted and coated with all the Tandoori Mayo Masala.

Ensure once it is cooked and lightly roasted, allow it to have a creamy texture. This will make your sub sandwich moist and delicious. Once done, turn off the heat and keep the Tandoori Mayo Paneer Tikka aside.

The final step is to assemble the Tandoori Mayo Paneer Tikka Sub Sandwich. 

Slit the panini breads into half (allow the joints to be held together, don't split it completely into two separate pieces).

Apply a little butter on the outer sides and toast it either in the oven (180 C for about 4 minutes) or on a skillet until lightly crisp.

Lay the toasted bread on a flat surface. Arrange the cucumber & tomato slices and sprinkle some salt and black pepper on it. Place a few shredded lettuce leaves over it.

Next place the tandoori mayo paneer tikka filling, place a few jalapeno pieces and ringed onions on the top.

Finally drizzle a tablespoon of Tandoori Mayo on the top and press the Sub Sandwich down and serve immediately.
