How to Hit 100g of Protein for Under $50 a Week (The “Inflation-Proof” Meal Plan)

Phase 1: The Math of Protein (Cost Per Gram)

Before we shop, we need to look at the numbers. We aren’t looking for the cheapest food; we are looking for the cheapest protein.

Here is the breakdown of Protein Per Dollar in late 2025 (based on average Aldi/Walmart prices):

• Dry Lentils: ~75g of protein per dollar (The MVP)
• Chicken Breast (Bulk/Frozen): ~33g of protein per dollar
• Eggs: ~25g of protein per dollar
• Milk: ~21g of protein per dollar
• Canned Tuna: ~20g of protein per dollar
• Ground Beef (Lean): ~18g of protein per dollar

The Strategy: You cannot rely on just one source. If you only eat lentils, you’ll get bored (and bloated). If you only eat beef, you’ll go broke. The secret is blending.

Phase 2: The $50 High-Protein Shopping List

This list assumes you have basic spices (salt, pepper, oil, soy sauce) in your pantry. We are shopping at a budget store like Aldi or Walmart.

The “Protein Anchors” ($35)

• 5 lbs Chicken Breast (Frozen or Bulk Pack): $15.00 (approx. 500g protein total)
• 2 Dozen Eggs: $6.00 (approx. 144g protein total)
• 2 lbs Dry Green Lentils: $3.00 (approx. 200g protein total)
• 2 Cans Tuna: $2.00 (approx. 40g protein total)
• 1 Gallon Milk (or Soy Milk): $3.00 (approx. 60g protein total)
• 1 Tub Gr[1]eek Yogurt (Plain/Large): $6.00 (approx. 90g protein total)

The “Volume & Flavor” ($15)

• 5 lbs Rice (Bulk bag): $4.00
• Frozen Spinach (2 bags): $3.00
• Bananas (1 bunch): $1.50
• Bag of Carrots: $1.50
• Tomato Sauce (2 cans): $2.00
• Oats (Canister): $3.00

Total Estimated Cost: ~$49.00
Total Available Protein: ~1,034g (Well over the 700g needed for the week!)

Phase 3: The Meal Prep Recipes

We aren’t cooking fancy. We are cooking for fuel and finances.

1. The “50/50” Meat Sauce (Budget Hack)

This is the oldest trick in the book to double your protein volume while halving the cost.
The Concept: You mix ground meat (or finely chopped chicken breast) with cooked lentils. The texture is almost identical, but lentils cost pennies.

2. “Adult Lunchable” Bistro Box

Stop cooking lunch. It’s annoying. Assemble this box in 5 minutes.

• 2 Hard Boiled Eggs (12g Protein)
• 1/2 Cup Greek Yogurt Dip (mix with ranch powder or herbs) (10g Protein)
• Canned Tuna mixed with a little mayo/mustard (20g Protein)
• Carrot sticks & a banana
• Total Protein: ~42g for roughly $2.50.

3. The “Inflation” Chicken Stir Fry

We use the frozen spinach here because it is nutrient-dense and cheap.

• Base: 1 Cup Rice
• Protein: 6oz Chicken Breast + 1 Scrambled Egg mixed in
• Veggie: 1/2 bag frozen spinach (thawed and squeezed dry)
• Sauce: Soy sauce + pinch of sugar + garlic powder
• Total Protein: ~45g.

Phase 4: A Sample 100g Protein Day

Here is what a full day looks like on this plan.

• Breakfast: “Pro-Oats”
  • 1/2 cup Oats cooked with 1 cup Milk ($0.40)
  • Mix in 1/2 cup Greek Yogurt after cooking ($0.80)
  • Protein: 20g
• Lunch: Tuna & Egg Box (Recipe above)
  • Protein: 42g
• Dinner: 50/50 Lentil & Chicken Stew over Rice
  • Protein: 35g
• Snack: Hard Boiled Egg
  • Protein: 6g
