- Knife
- Chopping board
Instructions
- Grate the zucchini using the coarse side of a box grater. Gently squeeze out some of the excess moisture with clean paper towels or a kitchen towel.
- Heat one teaspoon of olive oil in a large skillet over medium-high heat.
- Add the shrimp, season lightly with salt and pepper, and cook for about 1½–2 minutes per side, until pink and opaque. Transfer to a plate.
- Add the remaining olive oil to the skillet.
- Cook the minced garlic for about 30 seconds until fragrant.
- Stir in the grated zucchini and cook for 3–4 minutes, stirring occasionally, until slightly softened but still tender.
- Add the lemon juice, lemon zest, Parmesan, and chopped parsley. Stir until everything is well combined.
- Return the shrimp to the skillet and toss gently for one minute.
- Finish with extra parsley, freshly ground black pepper, and a pinch of red pepper flakes if desired.
- Serve immediately with a lemon wedge on the side.
Meal Prep Tips
- Grate the zucchini up to two days in advance and store it in the refrigerator.
- Buy peeled, deveined shrimp to save prep time.
- Measure the garlic, Parmesan, and seasonings ahead for an even faster dinner.
Storage
Store leftovers in an airtight container in the refrigerator for up to 2 days.
Because shrimp cook quickly, avoid reheating for too long to prevent them from becoming rubbery.
Freezing is not recommended after the zucchini has been cooked, as its texture becomes watery.
Easy Swaps
- Replace shrimp with diced chicken breast.
- Use grated cauliflower instead of zucchini.
- Add baby spinach during the last minute of cooking.
- Swap Parmesan for Pecorino Romano.
- Finish with fresh basil instead of parsley for a different flavor profile.

Scaling the Plan
Cooking for more people? Simply multiply every ingredient by the number of servings you need.
For meal prep, doubling or tripling the recipes works especially well. The overnight oats, roasted sweet potatoes, and cooked chicken all keep well in the refrigerator for several days.
Frequently Asked Questions
Can I prepare the whole meal plan ahead of time?
Yes. All three meals are meal-prep friendly. The overnight oats last up to three days, the BBQ chicken bowl keeps well for three days, and the shrimp dinner is best enjoyed fresh but can be refrigerated for up to two days.
Can I freeze these recipes?
The BBQ chicken and roasted sweet potatoes freeze well. The overnight oats and zucchini rice are best made fresh, while cooked shrimp can lose texture after freezing.
Is this meal plan high in protein?
Yes. The combination of Greek yogurt, chicken breast, and shrimp provides approximately 90–95 grams of protein across the day.
Can I swap the protein sources?
Absolutely. Chicken, turkey, tofu, salmon, lean pork, or beans can all be substituted while keeping portions similar to stay close to the calorie target.
Are the calorie counts exact?
No. All calorie values are estimates based on commonly available ingredients. Different brands and portion sizes may vary slightly.
