Plant-Based Sunday Meal Prep for Busy Families — 5 Days of Lunches and Dinners Under $15 Total

Sunday meal prep for a family is not about cooking everything in advance. It is about eliminating the decision and the active cooking time on the evenings when both are in shortest supply. A 75-minute investment on Sunday afternoon produces five days of ready-to-heat lunches and dinners that take 5 minutes to serve on weeknights — less time than ordering takeout, a fraction of the cost, and significantly more nutrition.

These three recipes are chosen specifically for their batch-cooking properties: they all scale easily, refrigerate well for 3–4 days, improve in flavor overnight, and cover different nutritional profiles across the week.

Note: All three recipes are fully detailed in earlier articles. Below we focus on the batch quantities, storage system, and weekly rotation.

Triple Bean Soup  —  10g protein · 10g fiber · $1.10/serving · 30 min · Article 24 & 40

Double batch quantities for a family of four: use 1.5 cans each of black beans, kidney beans, and chickpeas; two large cans of diced tomatoes; and 4 cups of vegetable broth. This produces 8 servings — two weeknight dinners for the whole family. Total cost for 8 servings: approximately $8.80. Reheats in 5 minutes on the stove or 2 minutes in the microwave. Gets noticeably better on day two as the beans absorb the spiced broth.

Hearty Protein Bowl  —  23g protein · 15g fiber · $1.85/serving · 25 min · Articles 8, 10, 19, 35, 37, 44

Batch-roast double quantities of tofu, chickpeas, and sweet potato on Sunday — two trays side by side at 400°F for the same 20-minute window. Store the roasted components separately from the raw zucchini ribbons and nut cheese. On weeknights, assemble bowls in 3 minutes: ribbons in the base, roasted components from the fridge (cold or quickly microwaved), nut cheese on top. The roasted components keep for 3 days.

Mason Jar Meal  —  12.5g protein · 10.9g fiber · $1.50/serving · 15 min · Articles 11, 13, 42

Assemble 4–5 mason jars at once on Sunday. The layering system — dressing at the bottom, grains in the middle, vegetables on top — keeps the dressing away from the vegetables until the jar is shaken before eating. Individual jars stay fresh for 2 days, which means make Monday–Tuesday jars on Sunday and Wednesday–Thursday jars on Tuesday evening in about 10 minutes.

The 75-Minute Sunday System

Running all three recipes simultaneously is what makes 75 minutes realistic for a week of food:

1. 0:00 — Start the Triple Bean Soup on the stove (sauté onion and garlic, 4 minutes).
2. 0:05 — Preheat the oven to 400°F. While soup simmers, prep tofu, chickpeas, and sweet potato for the Hearty Protein Bowl.
3. 0:15 — Two trays of Hearty Protein Bowl components go in the oven. While they roast, stir the soup and prep mason jar ingredients.
4. 0:35 — Bowl components come out of the oven and go into storage containers to cool. Assemble 4–5 mason jars.
5. 0:50 — Soup is done. Cool and portion into family containers. Label everything.
6. 1:15 — Fridge is stocked. Clean up. Done.
