Grilled Shrimp Nachos

De-vein, peel, and remove tails from 1 1/2 pounds of large shrimp (jumbo tiger prawns are a great choice). In a large bowl, toss shrimp with 1/4 cup extra virgin olive oil, juice from 1 lemon, salt, and pepper. Let marinate for about 1/2 hour while you heat up the grill to medium-high heat. Grill shrimp on each side until they turn pink, about 5 minutes total, depending on size. Set grilled shrimp aside.

Roughly chop 3 vine tomatoes, 1 red onion, 1/4 Serrano chili, 4 to 5 radishes, and 1/2 bunch of fresh cilantro leaves. Add above ingredients along with juice from 1/2 lime, 1/4 cup of extra- virgin olive oil, and salt and pepper into a food processor and pulse . Take the shrimp and add it to the salsa in the food processor. Pulse until well combined but still chunky.

Take a medium saucepan and melt 4 tablespoons of unsalted butter over medium heat. Add 4 tablespoons of all purpose flour and stir well with a wooden spoon. Do not let the flour take on any color. Take a whisk and stir the roux while you slowly add 2 cups of whole milk. Let it come to a simmer and thicken up, it should take about 5 minutes.

Add 1 1/2 cups shredded cheddar cheese to the roux, season with salt and pepper and set aside.

Heat corn tortilla chips in the oven, as desired. Scoop a generous heaping of cheese sauce onto chips. Pour shrimp salsa over the chips and cheese. Garnish with any remaining shrimp, fresh lime wedges and some fresh cilantro.
