// Recipe generation workflow
const generateRecipe = async (ingredients, preferences) => {
  const prompt = `
    Generate a creative recipe using these expiring ingredients: ${ingredients.join(', ')}
    Dietary preferences: ${preferences}
    Include: title, description, ingredients list, instructions, prep time, cook time
  `;
  
  const response = await sambanovaClient.chat.completions.create({
