If using jumbo shrimp or 16 oz. shrimp, follow same instructions as regular shrimp, cooking until shrimp reaches minimum internal temperature.
If using diced chicken, pat dry and season all over with 1/4 tsp. salt and a pinch of pepper. Follow same instructions as shrimp in Step 3, stirring occasionally until browned, 4-5 minutes. Follow same instructions as shrimp in Step 4, cooking until chicken reaches minimum internal temperature.
If cooking without a protein, omit end of Step 1 and Step 3. Place a large non-stick pan over medium-high heat and add 2 tsp. olive oil. Add shallot and garlic and cook until aromatic, 30-60 seconds. Continue to Step 4.
