Marinated Beef Tips with Potatoes

Ingredients

• 1 1/2 lbs. sirloin beef tips
• 2 cloves garlic, minced
• 2 Tbsp. lime juice
• 1/2 cup olive oil
• 1/4 tsp. red pepper flakes
• sea salt and pepper to taste
• 1 pound white- or yellow-flesh potatoes
• 3 Tbsp. olive oil
• 1/2 tsp. paprika (optional)
• 2 Tbsp. grated Parmesan cheese (optional)

Instructions

1. Whisk together the minced garlic, lime juice, 1/2 cup olive oil, and red pepper flakes. Cut beef tips into 2-inch chunks and season lightly with sea salt and pepper. Toss beef tips in the marinade, then place in a resealable plastic bag and refrigerate for at least 4 hours, or up to 24 hours. Heat grill over medium-high heat.
3. Preheat oven to 425 degrees F. Slice potatoes 1/4 inch thick. Season potatoes with sea salt, pepper, and paprika. Toss the potatoes in 3 tablespoons olive oil. Spread them out in a single layer on a foil-lined baking sheet. Bake for about 15 minutes, until cooked through and starting to brown. Remove from the oven and sprikle with Parmesan if desired. Meanwhile, grill the sirloin tips to desired doneness, discarding excess marinade
