In a large bowl, combine ground meat, cheese, grated garlic, Italian seasoning, bouillon cube, red pepper flakes, chopped cilantro & some black pepper. Combine well & form into meatballs.
In a large skillet, over medium-low heat, melt 2 Tbsp butter. Cook meatballs for 8-10 minutes until browned & cooked through. Add pasta sauce & continue cooking until sauce is hot. Remove to a bowl & keep hot while you saute your parsnip noodles.
In the same skillet, melt remaining Tbsp butter; add lemon juice, hot sauce & minced garlic. Add the spiralized, parsnip noodles & saute for 3-4 minutes, stirring regularly, until parsnips are tender-crisp. Adjust seasoning with salt & pepper.
Divide parsnip noodles between serving plates & top each with meatballs & sauce.
